Sanso for B2B Services: Invoicing and Collections

The Problem B2B Service Companies Face

Financial management for B2B services almost always ends up on the back burner. Every project has its own billing terms. Every B2B client pays at their own pace, often at 30 or 60 days. And in the meantime, someone has to rebill the expenses you've advanced, keep track of subcontractors, and chase late payments without ruffling any feathers. I'm Amalia Bercot, co-founder and CEO of Sanso, and that's exactly the work our AI-powered service takes over.

In a services company, your team's time is your margin, plain and simple. Every hour spent putting together an invoice, checking a subcontractor's bill, or running after a payment is an hour that doesn't go to a client. And the most uncomfortable part: the person chasing the payment is very often the same person who sold and delivered the project. Mixing the business relationship with money always gets a little awkward. The result: follow-ups drag, work that was genuinely delivered slips through the cracks, and cash flow tightens.

Then there's the lack of visibility. Without up-to-date project profitability tracking, it's hard to say which client actually makes you money once you subtract team days, rebilled expenses, and the cost of external providers. You steer by gut feel, even though the data exists. It's just scattered all over the place: in emails, quotes, bank statements, the accounting tool. And between 5 and 50 employees, the volume doesn't yet justify hiring a full-time finance person. Growth, meanwhile, still demands rigor.

Sanso: AI-Powered Financial Management for B2B Services

Sanso is an AI-powered financial management service for B2B service companies. The AI is what does the work: it creates and sends your invoices, captures and validates your supplier invoices, runs collections, and reconciles your accounts in real time. It's not software you operate on your own. It's a service that takes over the operations for you.

So there's nothing new to learn. Sanso's AI runs in the background, inside the tools your company already uses: your accounting software like Pennylane, your bank like Qonto, your Google Workspace, your CRM. The results land in your own tools, and you talk with our team a bit like you would with a trusted provider, by email or WhatsApp.

The idea fits in one sentence: you delegate financial operations, the AI handles them continuously, and your teams keep their minds on projects and growth.

The Financial Challenges Unique to B2B Services

B2B Invoicing That Changes from One Client to the Next

A services company rarely invoices two clients the same way. Fixed fee, time and materials, pre-sold days, milestone billing, rebilled expenses: every contract carries its own rules. B2B invoicing, at its core, means sending the right invoice at the right time, for the right amount, to the right entity, without ever forgetting work that's already been delivered. That's a level of rigor nobody really has time to keep up between client emergencies.

B2B Collections That Go Beyond Simple Reminders

Your clients are businesses, and businesses pay at 30, 45, or 60 days, sometimes longer. B2B collections take real follow-through: an automated email sequence stops working the day a client disputes an amount, demands a purchase order on the invoice, or wants another entity billed instead. At that point you need someone to take each case end to end, especially when the person involved is also the one who has to protect the business relationship. Otherwise, the unpaid invoice drags on and your DSO climbs.

Expenses and Subcontractors to Track Closely

Services companies lean heavily on freelancers, subcontractors, and expenses advanced on the client's behalf. Every supplier invoice has to be collected, checked (amount consistent with the quote, no duplicates), then attached to the right project. And billable expenses have to be recovered without losing any along the way. Done by hand, all of this is time-consuming and fragile. At the end of the day, it's margin evaporating.

Project Profitability You'd Finally Like to Track

Knowing what each project actually brings in requires up-to-date cost accounting: team days, expenses, subcontracting, all attached to the right client and the right project. Everyone wants it, almost nobody keeps it up, for lack of time. And you end up discovering the low-margin projects far too late, once the year-end accounts are on the table.

What Sanso's AI Handles

The AI Creates and Sends Your B2B Invoices

Sanso's AI spots when a project is finished and needs to be invoiced, then creates the invoice according to each client's specific terms. It also combs through your quotes to flush out the ones that haven't been invoiced in full, and follows up when needed. The goal: no delivered work left forgotten, knowing that in small businesses nearly 5% of invoices are simply never created. The work got done, but nobody thought to bill it.

The AI Runs B2B Collections for You

The AI runs personalized, multichannel B2B collections (email, SMS, phone), not a mindless blast of automated reminders. It tracks in real time who has paid, what's pending, and what's stuck. A client disputes an amount? The case gets checked against the quote in the CRM, or confirmed with the salesperson. They flag a billing-entity error? The AI reissues the correct invoice and follows the payment until it lands. Your DSO drops, and your teams no longer have to take on the thankless job of chasing their own clients.

The AI Captures and Categorizes Your Supplier Invoices

The AI fetches your supplier invoices wherever they land: it reads your inbox and pulls out the actual invoices, connects to supplier portals (SaaS tools, subcontractors, suppliers of all kinds) to download the documents, and picks up anything sent to a dedicated WhatsApp channel. It reads them, hunts for duplicates, checks consistency against the quote, then attaches each expense to the right project. Your per-client and per-project cost accounting finally becomes usable, without a single entry on your side, and billable expenses stop getting lost along the way.

The AI Reconciles Your Accounts in Real Time

For every bank transaction, the AI identifies the purchase or sales invoice that goes with it. You know at any moment which clients have paid and which are late, you never pay the same supplier invoice twice, and you have the reliable data you need at hand to calculate VAT. Your bank reconciliation stays up to date without anyone having to tick off each line.

AI Supervised by Humans

Everything rests on an AI that learns how your company operates over the months. But on sensitive matters, it never works alone: our operators supervise, handle exceptions, and make the call on the tricky cases. Between 80% and 99% of the work is automated, with 100% reliability.

How It Works

1. Onboarding. Within a few days, the AI plugs into your existing tools (accounting, bank, CRM, Google Workspace) without disrupting anything in your business.
2. The handoff. The AI starts invoicing your work, collecting unpaid invoices, capturing your supplier invoices, and reconciling your accounts, across the scope you delegate to it.
3. Your rules. You set what matters: invoicing terms per client, accounts that need careful handling, follow-up thresholds, and the approvals you want to keep before an invoice or a payment goes out.
4. Continuous work. The AI runs 24/7, with no vacations and no sick days. Nothing piles up, nothing falls through the cracks.
5. Your visibility. You find everything in your own tools, and you write to our team by email or WhatsApp whenever a need comes up.

The Results You Can Expect

Time back for your teams. The hours spent putting invoices together, chasing unpaid invoices, and checking subcontractor bills go back where they create value: projects and growth.

Cash flow that can breathe. Every service is invoiced without omissions, unpaid invoices are collected without hesitation, billable expenses are recovered. Your DSO drops and your cash becomes predictable again.

Profitability that's finally readable. The cost accounting keeps itself up to date, and you see clearly which project and which client actually make money, once every cost is attached.

No HR risk. No finance hire to recruit and then manage, no service interruption during vacations. The monthly retainer runs from $300 to $2,000 depending on your volume of operations, with no per-transaction billing, and there's no commitment: you stop whenever you see fit.
