Scaling up Commercial Fit-Out Business from £5M to £15M in 12-18 Months

£15m turnover comes from pipeline coverage, not from pricing more tenders.

Think of your workload like a vending machine. You don't get sales by shaking it. You get sales by filling the right slots and keeping them full every week. Your "slots" are your lead sources. Your "stock level" is live, qualified opportunities.

Lead engine

A repeatable system that creates, qualifies, and progresses opportunities to award, with weekly activity targets per lead source.

Pipeline cover

Total value of live opportunities you are actively working, divided by your turnover target. For fit-out growth planning, use 3x cover.

Tender

Your priced offer to do the work, including scope, exclusions, programme assumptions, prelims, and commercial terms.

Prelims (Preliminaries)

Time-related site costs like site supervision, welfare, access, temporary protection, temporary electrics, hoarding, and set-up. They burn every week the programme runs.

3x cover is the number that stops desperation bidding. To land £15m in the next 12 months, you need about £45m of live, qualified opportunities if you win 1 in 3. Carry only £15m to £20m in the pipeline and every lost job forces you into rushed tenders, squeezed prelims, and taking programme risk you cannot price.

Allocate the £45m across three sources

Three lead sources beat ten because each source changes margin, conversion speed, and hassle. But "use three sources" is useless without a target split. Here is one that works for a £15m fit-out contractor growing from a repeat-client base:

That gives you roughly 56 live opportunities at any time. The repeat-client slice is heaviest because those jobs convert fastest and protect margin. If your business leans more on Main Contractor work, shift the weight, but never let one source exceed 50% of pipeline or a single lost relationship blows a hole in your year.

Turn the split into weekly activity targets

A pipeline doesn't fill itself. Each source needs a weekly input that a director or BD lead can hit without cancelling delivery meetings. Here is a worked example for the 12-month plan above:

Treat missed activity like a missed procurement deadline. Skip a month of consultant catch-ups and you'll feel it 10–14 weeks later as a gap in your tender list, which turns into idle labour and an empty programme slot you can't fill at short notice.

Stage-gate the pipeline so you stop lying to yourself

£45m of "early chats" is not a pipeline. Split your £45m into three bands and set a target value for each. The flow below shows how opportunities must move left to right, with a clear £ target per band:

Review these bands every Monday. The diagnostic is simple. If "priced and submitted" sags below £12m, you have a conversion problem and need to chase decisions harder. If "early chats" drops below £10m, your weekly activity has slipped and you're heading for a dry patch in Q3. Managing this split in Archdesk's pipeline view means each band updates automatically as you log tender submissions and valuations against opportunities, so the weak stage shows up the same week it opens rather than at a quarterly board review.

Make it real this week: 6-step set-up checklist

1. Create three pipeline stage fields in your CRM or tracker: "Early Chats", "Invited & Scoping", "Priced & Submitted". Tag every live opportunity into one band today.
2. Set £ targets per band: £15m in each of the three bands. Pin these numbers to the wall or your Monday dashboard. If any band drops below £10m, it's a red flag.
3. Write a Monday review agenda (15 minutes max): (a) total value per band vs target, (b) which opportunities moved stage this week, (c) which weekly activities were missed, (d) one action per source to refill the weakest band.
4. Assign weekly activity owners: name the person responsible for each source's weekly targets (5 client calls, 2 consultant catch-ups, 1 MC meeting). Put it in their diary as a recurring task.
5. Add a "win theme" field to every opportunity: one line, 12 words max. Example: "We delivered their last two floors, they trust our M&E coordination." No win theme = don't tender.
6. Book the first Monday review for next week: 9am, 15 minutes, same room, same three questions. The engine only works if you run it every week without exception.

Your concurrency cap tells you how many live jobs your team can handle. Cash tells you how many you can actually fund. Wages and suppliers don't wait for certification, so the real limit on growth is often your bank balance, not your headcount.

Take a worked example: a £1.2m Cat-B office fit-out in Birmingham on a 12-week programme under a typical JCT sub-contract. You apply monthly, retention is 5%, and you're paid 30 days after the Interim Certificate. The Main Contractor issues a payless notice against your Month 2 application.

1. Start with the job's planned commercial rhythm. You plan to earn £400,000 of value per month (£1.2m over three valuation points at weeks 4, 8, and 12).

   Your cash cost burn is £85,000 per week for labour, materials, hoists, waste, and sub-sub-contracts. Over four weeks, that is £340,000 paid out before any money lands.

2. Month 1 creates the hole, even with a "clean" valuation. You apply for £400,000 at week 4. The QS certifies £400,000. Retention is 5% (£20,000), so the net due is £380,000. Payment falls 30 days after certification, so the £380,000 lands in month 2, not month 1. During month 1 you receive £0 and pay out £340,000.

3. Month 2 shows how certification friction turns into a bank problem. You apply for another £400,000 at week 8. The QS certifies £392,000 because £8,000 of ceiling changes aren't backed by signed dayworks and marked-up drawings. Retention on the certified amount is £19,600, so the net due before any payless notice is £372,400.

   Then the Main Contractor serves a payless notice for £31,250 citing "missing O&M manuals" and "photo evidence not provided". That reduces the month 2 payment to £341,150. But this payment falls 30 days after certification, so it lands in month 3, not month 2.

   The only cash you receive during month 2 is the £380,000 from your month 1 certificate (which was certified at week 4, due 30 days later, landing around week 8). You spend another £340,000 in month 2.

4. Month 3 finishes the work, but cash still lags behind Practical Completion. You apply for the final £400,000 at week 12. The QS certifies £400,000 less £20,000 retention, so £380,000 net. That £380,000 is due 30 days after certification, which means it lands around week 16, four weeks after the programme ends. During month 3, the only cash received is the £341,150 from the month 2 certificate. You pay out another £340,000.

5. See the full timeline. The diagram below maps every key commercial event across weeks 0–16. Each row shows a different activity: when you apply, when the certificate is issued, when a payless notice hits, and when cash actually arrives in your account.

   Read this timeline from left to right. Your first application goes in at week 4, but the cash from that certificate doesn't land until week 8. That four-week gap is why month 1 is entirely self-funded. Notice the payless notice at week 10: it knocks £31,250 off your month 2 certificate, and that reduced payment doesn't reach your bank until week 12, the same week the programme ends. Your final certificate payment arrives at week 16, a full month after you've handed over the project.

   The table below puts pounds to each of those moments.

   Month	Certificate settling this month (origin)	Cash received in month	Cash costs paid in month	Net cash movement	Cumulative cash position
   1	None (no prior certificate)	£0	£340,000	-£340,000	-£340,000
   2	Month 1 cert: £380,000	£380,000	£340,000	+£40,000	-£300,000
   3	Month 2 cert: £341,150 (after payless)	£341,150	£340,000	+£1,150	-£298,850
   4 (post-PC)	Month 3 cert: £380,000	£380,000	£0	+£380,000	+£81,150

   Your worst cash position is -£340,000 at the end of month 1. You don't break even until month 4, after the programme has finished and the final certificate settles. The £59,600 retained (£20,000 + £19,600 + £20,000) often sits with the Main Contractor until the Defects Liability Period ends (commonly around 12 months, depending on the contract).

6. Convert the worst point into a buffer target you can plan for. Your lowest point is -£340,000 at end of month 1. At £85,000 per week burn, that is 4.0 weeks of cash you must carry per live job. Run two of these jobs concurrently and you need £680,000 of working capital before either pays a penny.

7. Stop payless notices becoming "normal" with a fixed evidence pack rule. The £31,250 payless notice in month 2 cost you £38,850 of extra cash drag at the point it hurt most (it pushed the month 3 receipt down to £341,150 instead of £372,400, keeping your cumulative position negative for longer). Every application should go in with: dated photos by area, signed dayworks sheets, delivery notes matched to drawing revision, and marked-up drawings showing what is complete. Build the pack weekly. Month-end scramble produces gaps, and gaps get turned into deductions.

5% retention is not the main cash drag on a 12-week fit-out. Timing is. The 30-day payment cycle means you fund month 1 entirely from your own pocket, and the payless notice stretches that funding gap right through to week 16. In Archdesk, each application's payment status tracks against its certificate date and due date, so your forecast updates the moment a payless notice is logged or a certificate value changes. That means the £298,850 cumulative deficit at month 3 shows up in your cash-flow projection the same week, not at the next quarterly board review.

Your tender guardrails stop bad work getting in. Weekly control stops good work turning bad once you hit your concurrency limit.

Situation

A 40-strong commercial fit-out contractor in the North West, £5.5m turnover, mostly Cat A and Cat B refurb for Main Contractors under JCT Design and Build sub-contracts. One QS, one contracts administrator, and two working foremen.

They won three jobs inside six weeks: £900k in Manchester (10-week programme), £650k in Leeds (8 weeks), and £420k in Liverpool (6 weeks). The constraint was not site supervision. It was commercial conversion. Site decisions were not turning into notified variations and properly evidenced applications.

What happened

Week 2 on the Manchester job, the ceiling grid changed on Level 3 after the lighting layout moved. The foreman pushed it through to hold the programme. Nobody issued a variation notice for 9 days. The "instruction" lived as a phone call and a marked-up print in a van.

Week 4, the first valuation went in at £260k. The Main Contractor certified £210k. The missing £50k was "no backup": no dated photos, no delivery tickets, no marked-up drawings, no diary notes tying work to an instruction.

Week 5, Leeds hit a clash between the existing fire alarm and new partitions. Two RFIs sat unanswered for a week. Drylining stacked up and weekend working was agreed verbally. The foreman booked 96 extra labour hours to catch up, but those hours had no commercial home. They were not tied to a notified variation or a programme instruction.

Week 6, the MD was staring at a cash squeeze. Wages and suppliers were due, but roughly £140k of earned value was sitting as WIP (work in progress, meaning value earned but not yet certified) because the paperwork wasn't there. The instinct was to hire another supervisor. The real issue was simpler: nobody owned the weekly handover from site facts to commercial paperwork.

The fix: a 45-minute weekly control meeting

They locked in one meeting per live job every Tuesday at 08:00, with a fixed agenda and a timer. The routine did the heavy lifting, not heroics at month end.

Step-by-step: from site fact to variation notice within 48 hours

The meeting only works if site teams capture the raw evidence first. Here is the exact sequence they followed, from the moment something changes on site to an issued notice.

What goes into the evidence pack

Every variation submission and every valuation line over £2,000 got the same evidence folder. The QS printed this checklist on the inside cover:

• Dated site photos (minimum two: before condition, completed work)
• Daily diary extract naming the instruction source and date
• Marked-up drawing showing the changed scope, overlaid on the contract drawing
• Timesheet extracts for the operatives involved, signed by the foreman
• Material delivery tickets or supplier invoices
• The variation notice itself, with proof of issue (email timestamp)
• A one-page pricing build-up: labour, materials, plant, each line with a rate source (BoQ rate, agreed daywork schedule, or supplier quote)

Example output: the ceiling grid variation

The Manchester ceiling grid change was the test case. The foreman logged the diary entry on Day 1 of the fix (9 days late, but the new rule started here). He photographed the revised layout against the original reflected ceiling plan. The QS issued a variation notice within 24 hours citing JCT DB Sub clause 2.14, describing the lighting layout revision as the cause, and noting "price to follow within 5 working days."

The costed submission came in at £4,820: 38 additional labour hours at the agreed daywork rate of £42/hr (£1,596), revised ceiling grid materials at £2,740 (supported by a supplier invoice), and 2 days of scaffold tower hire at £242/day (£484). Each line cross-referenced a diary entry, a photo, and a delivery ticket. The Main Contractor agreed £4,650 within 10 days. Under the old approach, this would have surfaced at month end as an unexplained cost line with no recovery route.

The weekly meeting agenda that ties it together

The agenda ran to 45 minutes with a timer. 10 minutes: programme look-ahead for the next two weeks. 10 minutes: labour hours versus tender allowance, flagging any trade where actuals exceed the budget by more than 10%. 10 minutes: RFI and variation log review, checking every open item has a notice issued or a response chased. 10 minutes: next valuation pack assembly, confirming which evidence folders are complete and which need chasing. 5 minutes: three actions maximum, each with an owner and a deadline.

Two rules changed the outcome inside 30 days. No variation sat un-notified for more than 48 hours, even if the price was "TBC". No valuation went in without the evidence checklist completed for each line over £2,000. Foremen owned evidence capture by Friday close using site diary and photo forms. The QS owned conversion by Tuesday close: notices issued, variation prices built, and the application drafted from a live evidence folder.

The result

Month 2 on Manchester, the application went in at £310k and certified at £295k, a 95% conversion rate, because the backup was there. Leeds recovered the weekend working as a variation because the 96 extra hours were tied to a dated instruction and a clear cause. In Archdesk, this weekly rhythm is anchored by the labour cost tracking and WIP reporting views, so the labour spike and the £140k WIP gap show up in-week, not at month end when the damage is already baked in.

A checklist of good habits is not a plan. A plan has dates, numbers, and checkpoints that tell you whether you're on track or drifting. Below is a week-by-week template you can adapt to your own firm, followed by a worked example for a Cat A/B fit-out contractor scaling from £5m to £10m turnover.

90-day plan template: four tracks, weekly checkpoints

Worked example: Cat A/B fit-out contractor, £5m to £10m

Take a commercial fit-out firm currently running £5m across three live Cat A/B projects (Cat A is the base build finish; Cat B is the tenant-specific fit-out). The team is one PM, one QS, and a contracts administrator. The target is £10m within 12 months.

• Pipeline, Week 2: Current pipeline is £9m (1.8x cover against £5m). Target pipeline for £10m turnover is £30m. Gap: £21m of qualified opportunities over 90 days, roughly £1.6m of new enquiries per week.
• Concurrency, Week 4: The PM is running three jobs. The cap is 2 jobs per PM before valuations (monthly assessments of work done) start slipping. The PM drops to two. The third job gets a temporary site lead reporting to the PM until the new hire arrives.
• Hiring, Week 8: Second PM starts. Onboarded by the existing PM on the simplest live job for two weeks. By Week 10 they take that job plus one new start. Total capacity rises to four concurrent projects across two PMs.
• Cash, Week 6: Overhead burn is £22k per week. Cash balance is £110k, giving 5.0 weeks of cover. Target is 6 weeks (£132k). The £22k gap closes if one outstanding certificate of £34k is chased and paid within 14 days. If it isn't paid, no new tender goes out that fortnight.

Action checklist

• Set pipeline cover at 3x by Week 12. A £10m turnover plan needs £30m of live, qualified opportunities. Measure cover ratio every Friday.
• Cap concurrency at 2 live jobs per PM. Freeze new starts if any PM exceeds this or if valuations go in late twice running.
• Start the constraining hire by Week 8. Name who onboards them in their first week. If the new hire isn't delivering independently by Week 12, delay the next project start.
• Maintain a cash buffer of 6 weeks' overhead. If the buffer drops below 4 weeks, defer the next tender submission until cash recovers.
• Submit valuations on the due date on 95% of jobs. Notify variations in writing within 48 hours on 90%+ of jobs. Track both weekly. In Archdesk, certificate and retention tracking updates the same day a valuation is entered, so the cash buffer figure stays current rather than waiting for a month-end spreadsheet.
• Run a fixed 45-minute weekly meeting with four numbers: valuation submitted (yes/no), certificate received (yes/no), variations notified this week, and next 14-day programme risk.
• Approve personally: any new client type, any tender below your margin floor, any payless notice response, and any programme recovery plan longer than two weeks.

What to learn next

• Cash forecasting by certificate and due date, because a job can show profit on paper while cash goes negative once certification slips by even a fortnight.
• Variation evidence packs, because a 48-hour notice without proof still ends as "not agreed". Build a minimum pack that site staff can produce in 15 minutes.
• Close-out and final account control, because phased handovers and snagging (the process of identifying and fixing defects before handover) decide Practical Completion dates and retention release.

£10m turnover changes your job. You stop running every project and start protecting cash and margin across four to six live sites while other people handle the day-to-day. Pin the four-track plan to the wall, check the checkpoint numbers every Friday, and growth stays predictable instead of turning into valuation chasing and weekend firefighting.
