The verdict in three sentences
For a renovation contractor, slow collection of deposits and balances weighs more on cash than the margin of an average job. An e-signed quote with a built-in payment link costs EUR 2,000 to 6,000 excl. VAT to set up in 2026, then a fraction of a percent per transaction. Observed result: DSO cut by about 25 days, without changing quoting software.
Why the money arrives late
In construction, the classic flow looks like this: PDF quote sent, paper signature scanned or posted back, deposit request by email, transfer made "when the client remembers". For the balance, the invoice goes out after handover, and chasing often starts after 30 days. Homeowners pay faster than property managers and businesses, but removing payment friction is the easiest factor to fix.
| Indicator (2026 order of magnitude) | Paper and bank transfer | E-signed quote + payment link |
|---|---|---|
| Quote signature time | 7 to 15 days | 1 to 3 days |
| 30% deposit collection time | 21 days | 2 to 5 days |
| Balance collection time | 45 days | 10 to 20 days |
| Manual reminders per job | 2 to 4 | 0 to 1 (automatic reminders) |
| Jobs started without deposit | 15 to 25% | under 5% |
| Overall DSO | 50 to 60 days | 25 to 35 days |
Payment methods and their 2026 fees
The payment link in the quote and invoice offers several methods. The right one depends on the amount: card suits homeowner deposits up to a few thousand euros, while instant transfer and SEPA direct debit become cheaper above that.
| Payment method | Typical 2026 fees | Time to credit | Recommended use |
|---|---|---|---|
| Card (European) | 1.4% to 1.8% + EUR 0.25 | D+1 to D+3 | homeowner deposits up to EUR 5,000 |
| SEPA instant transfer (payment initiation) | EUR 0.5 to 1 per transaction | seconds | deposits and balances up to EUR 100,000 |
| SEPA direct debit (mandate signed with quote) | 0.5% to 1%, capped | D+2 to D+5 | balances and instalments |
| Standard transfer with dedicated reference | EUR 0 to 0.5 | D+1 | property managers and business clients |
| Pay in 3 or 4 instalments | 2.5% to 4% | D+2 (full amount) | homeowners, EUR 1,000 to 6,000 |
| Cheque | EUR 0, but 20 to 30 min handling | D+3 to D+10 | phase out gradually |
On a EUR 6,000 deposit, card costs about EUR 100, instant transfer under one euro. Offering both with instant transfer as the first choice sharply cuts average fees.
Integration budget
Most construction quoting tools offer e-signature, sometimes a payment module. When that falls short, a custom integration connects the quoting software, a payment provider and accounting.
| Item | 2026 range (EUR excl. VAT) |
|---|---|
| eIDAS-compliant e-signature built into the quote | 500 to 1,500 (plus EUR 1 to 3 per signature) |
| Deposit and balance payment link (card, instant transfer) | 800 to 2,000 |
| SEPA direct debit mandate and schedule | 400 to 1,200 |
| Automatic email and SMS reminders | 300 to 800 |
| Automatic reconciliation with accounting | 400 to 1,500 |
| Total | 2,000 to 6,000 |
Implementation time: 2 to 5 weeks depending on how open the quoting software is (API available or file export).

Frédéric, managing director of a 25-employee renovation company in Bordeaux, turns over EUR 3.6M a year, about EUR 300,000 invoiced a month. With a 55-day DSO, receivables stand at about EUR 550,000. After a EUR 4,800 excl. VAT integration, DSO falls to 30 days: receivables drop by about EUR 250,000. At 5% overdraft or factoring cost avoided, that is EUR 12,500 a year. Extra payment fees, with 70% of amounts paid by instant transfer, stay under EUR 3,000 a year. Estimated net gain in year one: about EUR 4,700, then close to EUR 9,500 a year, plus 6 hours a week of chasing saved.
FAQ
Can we require the deposit before starting work?
Yes, if the quote states it clearly. With a payment link attached to the signature, over 90% of deposits are paid within 5 days, which limits jobs started on overdraft.
Is there a limit on instant transfers?
The limit depends on the client's bank, often EUR 15,000 to 100,000 per transaction in 2026. Above that, standard transfer or SEPA direct debit takes over.
Is an e-signature as valid as a paper signature?
Yes, a simple or advanced electronic signature compliant with the eIDAS regulation is admissible. Budget EUR 1 to 3 per signature depending on the provider and level chosen.
Do we need new quoting software?
Usually not: if the software has an API or export, integration costs EUR 2,000 to 6,000 excl. VAT. With no openness at all, a connected quoting tool is an option from EUR 50 per user per month.
How do we handle progress billing on large jobs?
Each monthly progress statement generates an invoice with its own payment link or direct debit date. Business clients paying at 30 days end of month get an automatic reminder on day 31.
