The verdict in three sentences
An effective late delivery penalty clause in a redesign contract sets 0.5 to 1% of the amount per week of delay, capped at 10%, applied only to milestones that depend on the agency. Since 62% of delays on web projects come from client-side content and approvals, each deadline must be conditional on the company delivering specific inputs. A 12-week contractual schedule with payment milestones tied to deliverables protects you better than a high penalty rate the agency will refuse or work around.
Usual amounts in 2026
For a mid-size company redesign billed between EUR 30,000 and 90,000, observed practices are fairly stable. Agencies readily accept a moderate, capped penalty; they refuse uncapped clauses, which could wipe out their margin on a single project.
| Parameter | Common practice 2026 | Clause seen as excessive | Note |
|---|---|---|---|
| Weekly rate | 0.5 to 1% of the amount | 2 to 5% per week | Above 1%, the agency pads its schedule |
| Cap | 5 to 10% of the total | No cap | A cap is almost always required |
| Grace period | 5 to 10 working days | None | Absorbs normal hiccups |
| Calculation base | Value of the late work package | Total contract value | Fairer and better accepted |
| How applied | Deducted from the next invoice | Separate payment | Simpler to manage |
| Early delivery bonus | Rare, 2 to 3% | Not applicable | Useful if launch date is critical |
| Termination for delay | Beyond 6 to 8 weeks | From 2 weeks | Protects against a stalled project |
On a EUR 60,000 contract, a 0.75% weekly penalty amounts to EUR 450 per week, capped at EUR 6,000. Enough to motivate the agency, not enough to make it fight every line.
Where delays really come from
Most delays do not come from the agency. Based on redesign projects tracked in 2025 and 2026, the breakdown looks like this:
| Cause of delay | Share of delays | Average delay caused | Contractual lever |
|---|---|---|---|
| Content not delivered (copy, photos, product sheets) | 38% | 3 to 6 weeks | Contractual delivery date, automatic milestone shift |
| Late approvals or repeated back-and-forth | 24% | 2 to 4 weeks | 5-day approval window, silence means acceptance |
| Scope changes mid-project | 15% | 2 to 8 weeks | Mandatory priced change order |
| Development delay on the agency side | 14% | 1 to 4 weeks | Late delivery penalties |
| Third-party integrations (CRM, ERP, SSO) | 9% | 2 to 5 weeks | Third-party supplier responsibility defined |
The first two rows, 62%, are on the client. A penalty clause with no matching client obligations will either be refused or neutralised by an agency that documents every content delay.
The 12-week contractual schedule template
Here is a balanced template for a 30 to 60-page redesign, to attach to the contract. Each payment milestone follows approval of the deliverable.
| Week | Agency deliverable | Client obligation | Payment |
|---|---|---|---|
| W1 | Scoping workshop, sitemap | Tool access, named contact | 30% on signing |
| W2 to W3 | Desktop and mobile mock-ups | Approval within 5 working days | None |
| W4 | Approved mock-ups | Delivery of 100% of content | 20% |
| W5 to W8 | Development, integration | Interim testing within 5 days | None |
| W9 to W10 | Full acceptance version | Consolidated defect list | 30% |
| W11 | Fixes, SEO migration | Final approval | None |
| W12 | Go-live | Signed acceptance report | 20% balance |
The key rule: if the client delivers content 10 days late in W4, everything after shifts by 10 days and no penalty is due for that shift. This symmetry is what makes the clause enforceable.

Mini case study
Thomas, marketing director of a 400-employee mid-size company in Lyon, has just come out of a redesign that ran 7 months late with no usable penalty. For the new EUR 72,000 redesign, he negotiates 0.8% per week capped at 8%, i.e. EUR 576 per week and EUR 5,760 at most, with a 5-working-day grace period. In return, he commits to delivering content in W4 and approving within 5 days. Result: delivery 9 days late, 6 of them attributable to the agency after the grace period, so a EUR 576 penalty deducted from the balance. Above all, the site goes live in 13 weeks instead of 40 on the previous project, roughly 27 weeks of extra leads.
FAQ
What penalty rate do agencies usually accept?
Most accept 0.5 to 1% per week with a 5 to 10% cap. Above that, they stretch their schedule by 20 to 30% to cover themselves.
Can penalties be combined with damages?
If drafted as a liquidated damages clause, it is in principle a fixed, full settlement. Under French law, a judge can reduce it if manifestly excessive (article 1231-5 of the Civil Code).
How do I stop the agency from always blaming my delays?
Keep a shared log of content deliveries and approvals with dates. A shared project management tool is enough and costs EUR 0 to 15 per user per month.
Is an early delivery bonus worth it?
Yes if your launch is tied to a trade show or campaign. A 2 to 3% bonus for 2 weeks ahead of schedule is modest compared with the cost of a failed launch.
After how much delay can I terminate?
A common clause allows termination after 6 to 8 weeks of agency-attributable delay, once the penalty cap is reached, with handover of all deliverables already paid for.
