Our best PrestaShop modules for B2B billing and collection
Three modules — and the insight that B2B selling is credit.
Selling B2B means giving credit — the customer pays on 60 days, and between delivery and the money you finance. The question isn't how you invoice, but how you consolidate, collect and prepare the 2026 reform.
Sound familiar?
A credit you give without seeing it
The customer pays on 60 days. Until then you're their bank — without having planned it.
One invoice per order, a B2B mistake
Ten orders, ten invoices, ten payments to chase. The business customer wanted one.
A deadline nobody thinks of
A forgotten deadline is an unpaid invoice. And the delay runs in weeks.
A reform turning into a deadline
From 2026, e-invoicing becomes mandatory. Whoever isn't ready can't invoice compliantly.

Selling B2B means giving credit
That’s the truth no invoice says out loud. A B2B customer doesn’t pay on the click — they pay on 30, 45, 60 days. Between the sale and the money arriving, you’ve delivered, invoiced and financed. You’re supplier and bank at once.
And one invoice per order is a mistake in B2B
Your business customer orders ten times a month and wants one invoice, not ten. Ten invoices means ten payments to chase, ten chances for a dispute, ten lines in their books — and in yours.
The right question isn’t “how do I invoice”
It’s: how do I consolidate, how do I collect without wrecking the relationship, and am I ready for e-reporting 2026. Three questions, one single cash flow.
How to choose
First, see the truth no invoice says out loud
Selling B2B means giving credit. The customer pays on 30, 45, 60 days — between delivery and the money arriving, you finance. You're supplier and bank at once, and a bank always knows who owes it what.
Then cut the friction — the consolidated invoice
A business customer orders many times and wants one invoice, not ten. A monthly invoice: one payment in, one line, one point of contact. It's the first, most visible win.
Then collect the credit — without straining the relationship
A forgotten deadline is an unpaid invoice. Automatic dunning turns it into a process: polite, scheduled, impersonal. You're not chasing money — the system is reminding of a deadline, and that changes everything in tone.
And prepare the 2026 deadline — e-reporting
From 2026, electronic B2B invoicing becomes progressively mandatory, along with transmission to a PDP. It's not a project, it's a date — and whoever isn't ready can no longer invoice businesses compliantly.
What you gain
The consolidated invoice B2B expects
A single monthly invoice per customer instead of one per order. Fewer lines, less dispute, one payment in.
Collecting without wrecking the relationship
Automatic dunning and late-payment penalties. Collecting becomes a process, not an awkward call.
The 2026 reform, already ready
E-reporting 2026 prepared: transmission to a PDP becomes an obligation, not an option.
The credit you keep in view
A customer paying on 60 days is a credit. You see who owes you what — in real time.
No deadline that slips
The reminder goes out when the deadline falls — not when you think of it. No payment forgotten.
The right metric
Not revenue. The average payment delay is the number that governs your cash flow.
From install to results
-
See the credit you give
The customer pays on 60 days. Until then you're their bank.
-
Consolidate the invoice
One monthly invoice per customer: one payment in, one line, no dispute.
-
Collect without straining the relationship
Automatic dunning: polite, scheduled, impersonal.
-
Prepare e-reporting
Mandatory from 2026. Prepare before the deadline falls.
-
Measure the right number
Not revenue. The average payment delay.
“We were selling well and still constantly short. The reason was simple: everyone paid on 60 days and nobody tracked the deadlines. Since dunning runs automatically, our average payment delay dropped by three weeks — without a single dispute.”
Frequently asked questions
Why is B2B selling a credit?
Because a B2B customer doesn't pay on the click, but on 30, 45 or 60 days. Between delivery and the money arriving, you've financed the goods. Every sale on terms is credit granted — and like any bank, you need to know who owes you what and when.
Why a consolidated invoice?
Because a business customer orders many times a month and wants one invoice, not ten. A consolidated monthly invoice means one payment in, one line in their books, one point of contact in a dispute. Ten invoices are ten times the friction.
Why automatic dunning?
Because a forgotten deadline is an unpaid invoice — and a B2B late payment runs in weeks. Automatic dunning turns collecting into a process: polite, scheduled, impersonal. You're not chasing money, the system is reminding of a deadline.
What does e-reporting 2026 change?
From 2026, electronic invoicing between businesses in France becomes progressively mandatory, along with e-reporting of certain data to a platform (PDP). Whoever isn't ready won't be able to invoice business customers compliantly. It's not a project — it's a deadline.
Which metric should I track?
The average payment delay — not revenue. You can sell a lot and still be short of cash if everyone pays on 60 days. That delay is the number that governs your cash flow — and the only one that truly measures a credit business.
Where do I start?
With the consolidated invoice, because it cuts the daily friction immediately. Then dunning, to collect the credit without straining the relationship. E-reporting last — as a deadline you prepare before it falls.
