Set up and track your payments, within Sodium.

Clients sign the letter of engagement and set up their direct debit in one go, right inside your Sodium proposal.

How it works

Send the proposal from Sodium

Pick the client, add your services and send the proposal. Direct debit is on for every proposal from your settings, and you can switch it off for a client who already pays you.

Client signs and sets up payment

Your client reviews the proposal and pricing, signs the letter of engagement and goes straight on to set up their mandate with Adfin. It's one flow, and it works on their phone.

See it on the client record

The client is created in Adfin automatically. Their billing tab in Sodium shows the mandate, with a link straight through to Adfin.

Built into the Sodium workflow

Mandate at proposal

The direct debit is set up when the client signs, not chased down afterwards.

On by default

Connect Adfin by signing in, then switch direct debit on for every proposal or off for a single client.

Existing clients

Send a mandate request straight from the client record, no proposal needed. You write the email.

Clients created for you

New clients appear in Adfin as they set up their mandate, with no re-keying.

Existing mandates

Already collecting with Adfin? Link your mandates to Sodium clients from one screen. Clients don't need to do anything again.

Card on file

Take the first payment by card, so the work can start before the mandate is live, then use card as a fallback.

Works with Socket

Start in Socket and the client comes through to Sodium with the Adfin set-up already done.

Free retries

Up to three attempts on a failed direct debit, with a card link as backup. You're only charged for successful payments.

Works alongside Xero and QuickBooks

Sodium posts your invoices to Xero or QuickBooks. Adfin picks them up, collects payment and posts it back for reconciliation. Your ledger stays where it is, and the proposal, the mandate and the payment stay connected from start to finish. Here's how to set it up:

Don't take our word for it

You could have the best [Finance team] in the world, but they’re not going to log on at three o'clock in the afternoon on a Sunday and send a reminder email, even if they know that’s when they usually pay, but AI within Adfin will do that.
We've got lots of people that say they're against Direct Debit. They're not. They're against paying monthly or paying quarterly. They just want to pay when they get an invoice.
If you've got those niggles about late payments and fees, and the ability to get people onto direct debit, I wouldn't hesitate to switch.
Working with Adfin feels like a dream scenario for a business owner - I've got a team of smart, dedicated people building software to solve my biggest business problems.
Our vision when we started Represent was to have all of our clients on direct debit. This is how we set expectations with our clients. You sign up, you sign the direct debit, and we start working together
The main thing I wanted was the automation of rental collections, and a single place where I can see who has paid, who hasn't paid and who's at risk. Adfin is giving me all of that.
I don't have to worry about trying to find what amount is owed - I just click send and I know that Adfin will sort out everything within that email - for me it was a huge game-changer.
We used to have 1 in 5 of our invoices paid late. Through the use of Adfin, that's now changed to 1 in 15. It makes our whole process more reliable.
We had 20 years of direct debit mandate history to wash through as part of this... the support we got in that journey was fantastic.
It's probably been the most effective method we've had for getting clients who didn't want to go on direct debit to sign up to more automated payments. Adfin's helped bring them onto a more automated payment method and change their mindset on paying.
We just send an email, here is your payment link, and clients love it. Whether it’s Apple Pay or credit card, they’ll just be double-clicking on their phone like they would with any other bill.
What’s been really helpful about Adfin is that you build a flow once, and it triggers automatic reminders and chasers, saving a huge amount of time, and more importantly mental headspace.
For a young, fast-growing firm, Adfin is the difference between guessing what's in the bank next month and knowing.
