The Problem:

When payroll is ready… but payments become the bottleneck

You’ve done the hard part: the payroll is final, the pay run is approved, and everyone expects to be paid on time. Then the upload fails. Your bank or payment portal throws back errors:

formatting issues

missing or incorrect codes

invalid bank details

unclear “file error” messages that take time to diagnose

So you spend hours reworking the file to match the platform’s exact template. When it finally goes through, you’re hit with extra requests for information—just to release the payments.

The outcome is always the same:

delays and operational stress

people not being paid on time

customers calling and escalating

pressure on your team and your contracts

Mass payments shouldn’t depend on whether your file matches a portal’s rules.

That's where we come in.

Frequently asked questions

01
What’s the difference between mass, bulk, and batch payments?

They’re often used interchangeably. In practice, they mean processing a high volume of payments in a structured run—usually from a file export.

02
Do you need our file in a specific template?

No. Send the export you can produce. We clean and optimise the file before processing.

03
What happens if a payment fails?

We notify you quickly with the reason (for example, incorrect bank details or a closed account) so you can correct the data and re-run.

04
Can you support weekly payrolls that change every week?

Yes — Mass Payments is designed for fluctuating pay runs (common with contract, temporary, and variable headcount workforces).

05
Do you provide reporting for reconciliation?

Yes. Statements can be provided in PDF and CSV format.

06
Why do you ask for documents during onboarding?

We’re FCA authorised and must complete onboarding checks. Doing this thoroughly helps avoid delays and repeated requests later.

07
Do you offer support outside business hours?

Where payroll deadlines demand it, clients value having fast access to the team. We’ll confirm the appropriate support coverage during onboarding.
