Challenge

As a new product preparing to enter the market, Yousend needed a financial core robust enough to support conversions, fees, reconciliations, multi-currency transactions, and identity management—all without compromise. 

Building such a system in-house would have drained time and resources from what mattered most: launching fast with confidence.

They needed something out of the box to help them move fast, and set a solid foundation for the team and product. And they chose Blnk Finance.

The criteria for a ledger partner

Yousend needed a fintech Core that could help them build their MVP fast, while checking all of the boxes on quality, compliance, and accuracy. Their top requirements were:

1. Double-entry accounting out of the box.
2. Multi-currency balances and transactions
3. Linking customer identities to the balances they own
4. Performing back-office operations with their data
5. Reconciliation across currencies
6. A smooth learning curve for the developers
7. End-of-day visibility.

Solution

Blnk’s open-source Core made it possible to test, audit, and deploy the solution before reaching out to us. After evaluation, they decided to go with Blnk, It had everything they needed to build and scale Yousend.

Multi-currency support

Managing four currencies — CAD, GBP, NGN, and KES — out of the gate while supporting transactions between these currencies, handling fees, and performing end-of-day reconciliation became easier to implement. 

“Blnk simplifies ledgers and money movement without unnecessary complexity,” Toni Akinmolayan, Senior Software Engineer.

Fast, hassle-free integration

Yousend deployed a development instance within hours and moved to production just a couple of weeks later. Blnk Finance helped the engineering team move swiftly: integrating payment providers for seamless deposit and payout flows, implementing several transaction logic, etc.

As Toni shared:

“Integration was seamless, and the fact that it's open-source adds flexibility. On top of that, Blnk is incredibly fast, making it a solid choice for high-performance financial systems.”

Easy to customize 

Yousend leveraged several of Blnk’s out-of-the-box features such as: bulk transactions, inflight handling, scheduled transfers, and overdrafts to rapidly implement a wide range of use cases.

They used Blnk’s flexible framework to manage customer transaction limits based on account type, track FX gains and losses, and much more.

Improved audits & compliance

Blnk’s advanced balance features, such as Balance Snapshots and Historical Balances, enabled Yousend to enhance their internal reporting and audit workflows. These tools allowed the team to generate precise account statements for users while maintaining full visibility into balance history.

With this level of traceability, Yousend strengthened their compliance posture and simplified end-of-day reviews, ensuring they could confidently meet audit requirements and regulatory standards.

Outcome

Yousend didn’t just avoid reinventing the wheel — they shipped faster, with more control and less risk.

Today, Yousend is now in production, and we are excited to continue to power their money movement as they build and scale. They built systems to:

1. Record, track, and reconcile FX transactions.
2. Create, manage and connect multiple balances to the same user.
3. Set up inflight transactions, and manage commit/void statuses.
4. Set, update, and reset transaction limits for each user balance created
5. … and so much more

A partnership that grows

As Yousend grows, they continue to expand the features powered by Blnk — from better ops tooling to more granular ledger controls. They are also early users of our Blnk Cloud, using our managed platform for observability, collaboration and back-office operations while continuing to self-host their Core.
