GeminiWe run CRM and billing on this kind of tool, not just in theory.
Most Sellsy trainings are run by people who read the docs the night before. At Hack'celeration it's the opposite: a pipeline that matches the sales cycle, quotes that convert into invoices, dunning that chases late payers on its own, that's our daily agency work. Everything we teach you, we configure on shipped projects. We know the traps (the default pipeline nobody touches, the badly set accounting export) because we've already solved them.
- We run our own CRM and billing on this kind of tool, not just in theory
- 1-on-1 format: the trainer adapts to your level, new rep or seasoned Sellsy admin
- We tell you when Sellsy isn't the right call (sometimes a CRM alone is enough and costs less)
- We start from your real account, your pipeline and your actual quotes, not a dummy example
Four pillars so your CRM gets used and your invoices get paid.
A badly configured Sellsy means an empty pipeline nobody opens, quotes that live in Word, dunning never launched. Most of the trouble comes from the config, not the tool. We pick up your real account and work through the four pillars together.
- CRM and pipeline
A pipeline that fits how you actually sell
A login shared by five reps is not a CRM. We build your Sellsy pipeline around your real cycle: stages that match your sales motion, custom fields that capture what matters, tracked lead sources, role-based views. Your reps open Sellsy and see their deals, not an empty grid they ignore by Friday.

A signed quote that becomes an invoice in one click
Sellsy's real edge over a pure CRM is billing inside the same tool. We set up your quote templates with electronic signature, the one-click conversion to invoice, recurring billing for subscriptions, and the pre-accounting export your accountant needs. The deal you sign becomes an invoice, then a paid line, without retyping anything elsewhere.

Reminders that run, and a DSO that drops
Unpaid invoices kill cash flow, and chasing them by hand never happens. We set up dunning sequences that escalate on your schedule, tied to each invoice status. Late payers get chased on their own, with no one thinking about it. You learn to wire these reminders yourself, because that's exactly the part teams almost never set up.

Sellsy wired into Stripe, your bank and your stack
Sellsy earns its place when it stops being an island. We connect it to Stripe so clients pay invoices by card, sync your bank feed for reconciliation, and link marketing so a form becomes a tracked lead. For the tools Sellsy doesn't cover natively, we bridge them through the API and an automation layer you drive, so data flows instead of being retyped by hand.

- A diagnosis of your pipeline, your quotes and your dunning
- The first fixes to make, in priority order
- The right 1-on-1 format for your level and team size
- An honest take: Sellsy or a standalone CRM for your case
Your Sellsy training, step by step.
Five steps, no skipping. Each one on your real account, with a clear deliverable. From the first session we go after what makes deals and cash leak. By the end, you run your CRM and billing without us.
- Step 1 · Account audit
We open your real Sellsy account and spot what's broken
First session, we share your screen and look at your account together. Does your pipeline match how you sell, or is it still the default template? Do your quotes live in Word? Are invoices going out late, reminders never sent? We list the real reasons deals and cash leak. You leave with a clear diagnosis and the list of fixes, in priority order. No theory, your real account.
- Step 2 · Pipeline and data
We build the pipeline and migrate a clean base
We build your Sellsy pipeline around your real cycle, with the stages, custom fields and lead sources that matter. Then we migrate your contacts, companies and history and dedupe them, so you start on a clean base instead of importing a spreadsheet of duplicates nobody trusts. You sign off on the pipeline and role-based views before your team starts working in it, so it reflects how you actually sell.
- Step 3 · Quotes, invoices and dunning
We wire the quote-to-invoice-to-cash flow
We set up your quote templates with electronic signature, the one-click conversion to invoice, recurring billing, and the pre-accounting export your accountant needs, French and EU rules included. Then the part most setups skip: automated dunning that escalates on your schedule. You practice on your real quotes. By the end, a signed deal becomes an invoice, a payment and a clean export, with no retyping.
- Step 4 · Integrations and API
We connect Stripe, your bank and your tools
This is where Sellsy gets powerful. We wire it into the rest of your stack: Stripe and card payment on invoices, bank feed for reconciliation, marketing so forms feed the pipeline. For the tools Sellsy doesn't cover natively, we bridge them through the API and an automation layer like n8n. Data flows on its own instead of being retyped by hand, with logging so you can see what synced.
- Step 5 · Autonomy
You run your CRM and billing without us
The number one goal: you become autonomous. By the end of the program, you know how to build a pipeline, send an e-signable quote, convert it to an invoice, set up your reminders and read what synced with your bank and Stripe. You no longer need an agency to run your Sellsy. And if you want to delegate the setup later, we also run a Sellsy agency, but that's not the point here.
Why train 1-on-1 with us.
- 300+Pros already trained on our tools
More than 300 people have gone through our trainings across France and Europe. Sales teams, finance, small-business founders. Not vanity numbers: people who got their pipeline back on track and stopped retyping invoices into a second tool.
- 4.7/5Rating across 334 verified reviews
Average rating of 4.7 out of 5, across 334 reviews. We won't promise everything will be perfect: you have to do the work on your real Sellsy account. But the 1-on-1 format makes the difference on a tool that touches your sales, your billing and your cash at once.
- 1:1A dedicated expert, not a class of 100
You're not a number in a webinar. A trainer opens your real Sellsy account, looks at your pipeline and your invoice templates, and works through your actual cases. We schedule sessions around your availability, replays included.

The questions we get the most.
What is a 1-on-1 Sellsy training?
An individual program with a Sellsy expert, not a class of 100 people. We open your real account, look at your pipeline and your invoice templates, and work through your actual cases: CRM, e-signed quotes, invoicing, dunning, integrations. You ask your questions live, the trainer adapts the pace to your level. We schedule sessions around your availability, and you leave with concrete actions every time. That's what makes the difference on a tool that touches both your sales and your cash.How much does the Sellsy training cost?
There is no single price. We connect you with a trainer certified by Hack'celeration, matched to your need and your level. It varies from one trainer to another, based on their profile and the format that fits your project.Sellsy or a standalone CRM: which one to pick?
It depends on your need. Sellsy is an all-in-one suite: CRM and pipeline, quotes with electronic signature, invoicing and recurring billing, pre-accounting export, dunning and marketing in a single tool. A standalone CRM runs your pipeline but leaves you billing elsewhere. If you want the signed deal to become an invoice and then a paid line without switching tools, Sellsy has a real edge. If you're a pure-sales shop with no billing need, a CRM alone can be enough and cost less. During the training, we help you decide based on your real case.Can Sellsy be integrated with Stripe, my bank or n8n?
Yes, and it's one of the big parts of the training. We connect Stripe and card payment so clients pay invoices online, sync your bank feed for reconciliation, and link marketing so a form becomes a tracked lead in the pipeline. For the tools Sellsy doesn't cover natively, we bridge them through the Sellsy API and an automation layer like n8n or Make. We build the flows together so your CRM, your billing and your stack share data instead of you retyping it by hand.Do I need to be technical to take the Sellsy training?
No, not necessarily. Sellsy has a visual interface to build your pipeline, send quotes and invoice. To go further (API, automation bridges), a bit of technical logic helps, but the 1-on-1 format is built exactly for that: we start from your exact level. New rep, we go step by step through the pipeline and quotes. More confident admin, we jump straight to dunning, the API and integrations. And you can run a good part of it no-code through n8n or Make without touching code if you prefer.Can Sellsy really replace my CRM and my billing tool?
For most French and EU SMBs, yes, and that's the whole point. Sellsy brings together CRM and pipeline, e-signable quotes, invoicing and recurring billing, pre-accounting export, dunning and marketing in one place. In training, we wire the full quote-to-invoice-to-cash flow so the deal you sign in the CRM becomes a signed quote, an invoice and a paid line without retyping it into a separate billing system. If your billing lives outside French and EU norms, Sellsy's billing strength matters less, and we'll tell you so.How does automated dunning work in Sellsy?
Sellsy can chase your unpaid invoices for you, and setting that up well is one of the fastest wins. In training, we build dunning sequences that escalate on your schedule (a first polite reminder, then firmer follow-ups) tied to each invoice status, so late payers get chased automatically without anyone on your team thinking about it. The result: a lower DSO and better cash flow without adding admin. And above all, you learn to wire them yourself, because that's the part teams almost never set up alone.Can you migrate our current CRM or tool into Sellsy?
Yes, and it's a central part of the training. We migrate your contacts, companies, deals and history into Sellsy, dedupe the duplicates that always pile up, and map your old fields onto the new pipeline so nothing important gets lost. The classic trap: importing a dirty base nobody trusts from day one. Starting on a clean base is the difference between a CRM your team actually uses and one it abandons. In 1-on-1, we walk through your migration step by step and test before switching over for good.Is the training online or in person?
100% online, over video, 1-on-1. You join the sessions from anywhere, we share your screen and your Sellsy account live. Sessions are recorded if you want to revisit them. The individual format means real interaction: you're not a number in a webinar of 100, the trainer answers your questions about your setup, your pipeline and your invoices. That's what makes learning concrete on a tool as complete as Sellsy.
