Introduction
If your bank balance swings wildly between paydays, you’re not alone. In renovations, your crew burns cash long before invoices are paid. The fix isn’t heroic sales—it’s a simple operating system for money on each job: predictable billing stages, upfront material coverage, clear terms, and firm follow‑up. This guide shows what to change, why it matters right now in Europe, and exactly how to implement it in a week.
You’ll get practical stages that fit jobs under €100k, a 5‑minute risk check before you accept a client, and wording you can plug into your proposals today.
Industry snapshot: Intrum’s 2024 European Payment Report shows SMEs wait well over a month to get paid, with many reporting delays beyond agreed terms. FIEC notes cash strain remains a top insolvency trigger in construction SMEs. Let’s build a system that survives those realities.
The Money Map For Small Teams
Cash control starts before you swing a hammer. Treat every project like a mini P&L with four checkpoints you can run from your phone.
- Scope-to-Cost Reality Check
- List the three biggest cost buckets: materials, labor, specialist subs. Add 10–15% contingency on materials for substitutions and waste.
- Confirm lead times so billing milestones land before expensive deliveries or labor spikes.
- Client Risk Grading (5-Minute Version)
- Signals: wants a rush start but avoids deposits; changes story about budget; slow replies on basic info.
- Green: approval in writing, accepts staged invoices, pays small “test” invoice promptly.
- Amber: wants flexibility; require tighter milestones and smaller batches.
- Red: refuses upfronts; either walk or insist on escrow.
- Working Capital Plan
- Aim for neutral cash by the time 40% of the work is complete. That means deposits and the first stage must cover big materials and first payroll.
- For €30k interior refurb: €9k direct materials, €13k labor, €2k subs, €6k overhead+margin. Plan for €9–12k in before week 2.
- Variations Discipline
- Price changes before work, even if it’s “just a small tweak.” Send a one‑paragraph scope note with price and a checkbox for approval.
- Update the billing plan when scope moves—don’t wait until the end.
Practical example: A Barcelona apartment refresh (€42k, 6 weeks). Result with a solid money map—30% deposit day 0; stage 1 at demolition completion; stage 2 post MEP rough‑in; final after punch list. Materials covered by day 5, crew paid weekly without dipping into the company float.
Pro tip: Schedule invoicing into site routines. Every Friday, snap progress photos, note percent complete, and trigger the next invoice if a milestone is hit. Five minutes beats five phone calls later.
Progress Payment Schedule Template
Staged billing makes revenue show up while the job is happening, not three weeks after. A reliable pattern for private renovation jobs under €75k is four to five milestones tied to visible progress.
A proven 4‑stage example (adjust percentages to your risk):
- Deposit: 20–35% on acceptance. Match deposits to early material exposure.
- Stage 1: 25–30% after demolition/strip‑out and layout confirmation. You’ve created momentum and spent heavily—collect.
- Stage 2: 25–30% after rough MEP completed and inspected. This is the second heavy cash moment; get it funded.
- Practical completion: 10–20% when the space is usable and snag list is documented. Keep the last 5–10% for closeout leverage.
How to size each stage in 10 minutes:
- List early big‑ticket items (windows, HVAC units, cabinetry). Add their delivery weeks.
- Put a milestone one week before each big delivery.
- Assign percentages so cash received before that date covers the purchase plus one payroll.
Explaining it to homeowners:
- “We bill in steps that match progress you can see. Each invoice comes with photos and a short note on what’s done. This keeps materials flowing and avoids delays.”
What top performers avoid:
- Monthly billing on short projects—it drifts.
- Single mid‑job invoice—too much gap.
- End‑loaded plans that leave you exposed for 70% of cost late in the job.

Materials Deposit Policy
Your supplier doesn’t wait; neither should you. A clear rule on materials protects your margin and speeds decisions.
Simple policy that works across France, Italy, and Spain:
- Upfront coverage: Collect the full cost of special‑order items before you place them.
- Standard stock: Cover at least 50% for bulk orders (tile, flooring, paint) and fold the rest into Stage 1.
- Proof: Provide the client a copy of the supplier quote on request and confirm delivery week.
Typical local expectations
- France: Homeowners are accustomed to a 30% acompte on acceptance and additional staged payments. For custom joinery and windows, full prepayment is widely accepted once specs are signed.
- Italy: An acconto of 20–30% is common; clients accept full payment in advance for made‑to‑measure elements tied to your order.
- Spain: Anticipos of 30–50% are normal in reformas; custom items are prepaid to avoid manufacturer delays.
Wording you can paste into proposals
- “Custom materials (windows, bespoke cabinets, stone) are ordered after client approval and payment of the related supplier amount. This keeps lead times on track and avoids rescheduling.”
- “Bulk stock orders over €2,000 require a 50% materials payment prior to delivery.”
Operational tips
- Bundle approvals: Don’t drip small orders; batch weekly to reduce admin and shipping costs.
- Delivery staging: Have long‑lead items land the week before install—avoid site storage and damage.
- Supplier terms: Ask for pro forma invoices and agree on return/restocking rules in writing.
Don’t skip: Send a quick status note on materials every Friday. “Tile confirmed for week 3; appliances paid and shipping week 4.” It reduces nervous calls and speeds payments.
Late Payment Interest Law Europe
When an invoice is overdue, clarity beats conflict. Across the EU, Directive 2011/7/EU sets a baseline: unless otherwise agreed and not grossly unfair, B2B terms are typically 30 days, and statutory interest applies after due date. The default interest rate is the European Central Bank reference rate plus at least 8 percentage points, and reasonable recovery costs can be charged.
What this means for small renovation firms
- Put the due date and interest policy on every invoice and in your contract summary. People pay what they understand.
- For consumers, be reasonable and clear. Many countries allow late‑fee clauses with fair rates; avoid punitive language. Your goal is prompt payment, not a courtroom.
- Public clients have stricter limits; private residential relies on clear consent and documentation.
Practical follow‑up rhythm
- Day 1 late: Friendly reminder with invoice link and photos confirming progress.
- Day 7: Short, firm message adding the late‑fee note per contract and offering a phone call to resolve snags.
- Day 14: Pause non‑critical works and send a revised schedule that resumes upon payment.
- Day 21+: Formal notice per your jurisdiction. For ongoing projects, make next milestones “cash on delivery.”
Market update 2025: The European Commission’s 2023 proposal to tighten payment rules is still under discussion. Expect pressure toward shorter terms and stricter enforcement. Keep your paperwork clean and your terms visible. Reference: European Commission materials on combating late payment and sector guidance from national SME bodies.
Smart move: Add recovery costs only after a human phone call. Most late payments are admin, not malice. The mix of professionalism and proof (photos, signed approvals) gets you paid faster than threats.
Pro tip: Track promised dates, not just due dates. If a client says “paying Friday,” make a note and confirm in writing. That note helps you decide when to pause work without burning goodwill.
Retainage Best Practices
Withheld sums at the end can wreck cash if you let them balloon. Keep retentions small, time‑boxed, and tied to clear acceptance.
Rules that protect your cash and your client
- Cap at 5–10% of contract value on private residential renos under €100k.
- Split release: half at practical completion when the space is usable; the rest after snag resolution within a defined window (often 14–30 days).
- Put a hard date for the final inspection in the program. Drifting inspections equal drifting money.
Define “done” in one page
- List rooms/areas, what “usable” means (power on, fixtures installed, dust protection removed), and photo evidence required.
- Agree snag categories: safety, function, finish. Safety items fixed before handover; function within 5–7 days; finish within 10–14 days.
Negotiation tips
- Offer an alternative: a small bank guarantee or reduced holdback if the client insists on higher retention.
- Show your track record: “In the last 50 projects, our average snag closure is 6 days. Here’s our routine.” Confidence reduces fear, fear creates big holdbacks.
Avoid the common trap
- Don’t allow retentions to cover unpaid variations. Variations are separate work with their own billing steps; price and collect them on approval or at the next stage, never at final only.
Second CTA: If you want retentions under control, use Donizo. Set your holdback rules once, attach photo proof at practical completion, and trigger automatic reminders for final release dates—so retention doesn’t turn into a free loan.
Frequently Asked Questions
How much upfront should I ask to cover materials?
Match the real exposure. For standard stock, collect around half before delivery; for custom or non‑returnable items, take the full supplier amount on approval. In France, Italy, and Spain, homeowners are used to deposits between 20% and 35% plus prepayment on bespoke items.
What billing stages work best on renovation jobs under €50k?
Four milestones work well: deposit, post‑demolition, post‑rough‑in, and practical completion. Size them around material and payroll peaks so you’re never funding the job. Keep the last step small—just enough leverage to close snags without starving your cash.
What can I legally charge for overdue invoices in the EU?
For B2B, statutory interest usually applies after due date, often the central bank rate plus at least 8 percentage points, plus reasonable recovery fees. For homeowners, use fair, clearly stated late‑fee clauses and focus on documented reminders and staged work pauses.
How do I explain staged invoices to homeowners?
Tie each invoice to visible progress and share photos. Keep the language simple: “We invoice when specific work is complete—demolition, rough services, finishes—so materials arrive on time and the schedule stays firm.” Most clients appreciate transparency and predictability.
Conclusion
Growing construction firms don’t win by working harder; they win by getting paid at the right moments. Build a simple system: staged billing tied to visible progress, upfront coverage for costly materials, clear terms on overdue invoices, and small, time‑boxed holdbacks. Add weekly communication with photos and short notes, and your client’s trust will rise while your cash stress fades.
