Secure money-moving software
Timeline Digital is a fintech software development company providing fintech software and app development services: payment platforms, lending systems, digital wallets and banking apps, built on double-entry ledgers with encryption and audit trails from the first commit.
Balances that will not reconcile, installments tracked in spreadsheets and high-value approvals on WhatsApp are where most finance teams start. As a fintech software development company, we build for a stricter bar than ordinary apps. A retried request must never move funds twice, a balance can never silently change, and every action has to leave an audit trail your assessor can read. We build with double-entry ledgers, AES-256 encryption, PCI-aware tokenization and idempotent payment flows from the first commit. The source code is yours on full payment.
Fintech software development is building the applications that move and manage money: payments, lending, digital wallets and banking. Timeline Digital builds them end to end on double-entry ledgers, idempotent transactions, encryption and audit trails, with PCI DSS requirements in mind, such as card tokenization; compliance is confirmed per project.
Timeline Digital holds no certifications. Every build starts with a free pilot of 2 to 3 key modules, and the source code is yours on full payment.
What every fintech build includes
Where it breaks today
Money software gets commissioned when the manual workarounds become a risk. Each problem below is paired with what the system does about it.
Balances that do not reconcile at month end
The system: A double-entry ledger where balances are derived from entries and never edited in place, so the books always tie out.
A retried request that charged a customer twice
The system: Idempotent payment endpoints, so a network retry or a double tap never moves money twice.
Loan schedules and installments in spreadsheets
The system: Repayment schedules, arrears and reminders generated by the system and posted to the ledger as they fall due.
High-value actions approved over WhatsApp
The system: Maker-checker approvals inside the system, with limits by role, so no single person moves money unchecked.
An auditor asking who changed a limit, and no answer
The system: An append-only audit log on every balance change, login, refund and admin action.
A legacy core that cannot take a new payment rail
The system: New rails and providers added through a service layer beside the core, then migrated in stages.
A white-label or banking-as-a-service platform and a custom build suit different products. This is how they compare on the questions founders and finance teams ask first.
| Question | White-label or banking-as-a-service platform | Custom fintech build |
|---|---|---|
| Time to first launch | Fast, on a ready-made product | Free pilot in about 2 days; the full schedule is set from your requirements |
| Product rules | Limited to the provider's configuration | Your own fee, limit, approval and repayment rules |
| Ledger and data | Held in the provider's system | Your own double-entry ledger and audit log |
| Running costs | Per-account or per-transaction platform fees | No platform licence; payment and banking providers charge their own fees |
| Compliance | Part of it is carried by the provider under its licence and programme | Built with PCI DSS and your regulator's requirements in mind; compliance confirmed per project |
| Source code | Stays with the provider | Transfers to you on full payment |
Many fintechs launch on a provider’s regulated rails for cards, accounts and payments, and build their own product and ledger layer on top.
Security in fintech is not a feature you add at the end. It is the shape of the architecture. We start by deciding what regulated data your product is allowed to hold and, more often, what it should never hold at all. Card numbers get tokenized through a provider like Stripe or Adyen, so raw card data never reaches your servers and your PCI DSS scope is reduced. Everything that does live on your systems is encrypted with AES-256 at rest and TLS in transit, with secrets kept in a managed vault rather than in code.
On top of that sits the part auditors care about most: an immutable, append-only audit log that records every balance change, login, refund and admin action with who did it and when. High-value operations require maker-checker approval, so no single account can move money or change a limit unchecked. KYC and AML screening run through vetted providers wired into onboarding. We hold no certifications and do not claim any. We build with the relevant requirements in mind, document the controls, and hand you an architecture ready for your assessor’s review.
Custom software built around the way your business works. Plan maps the money flows, the regulated data and the threat model; the pilot modules run on the encrypted data layer, role model and audit log from day one; and Build & Scale adds the remaining payment flows and reconciliation, then security testing, a penetration test where your rules call for one, and a staged go-live.

Free. You choose 2 to 3 key modules and we build them first, so you can judge our work.
The full project starts only after you approve the pilot.
From approved pilot to complete digital system.
Full development, testing, deployment, training and support, built to grow with you.
Fintech covers a wide range, and each product type has its own hard part. We design each one around the money flow and the rules that govern it.
Many of these sit alongside a wider system. If you also need internal operations tooling, see our custom ERP software work, or read how we scope a build end to end on our process page.
We have no published fintech case study, and we will not imply a fintech portfolio. What we can show is the architecture money software relies on: role-based access, audit logging, approval workflows and payment-gateway integration. Our own free Timeline Installment Manager and Timeline Invoice handle installment schedules, receipts and overdue tracking for small businesses (not regulated fintech), and our published public-sector platform in Qatar shows roles, audit and approvals at scale. The free pilot lets your team test the core money flow before committing.
Delivered remotely from our Islamabad headquarters, with scheduled video meetings in your working hours; on-site visits only when agreed in the contract.
Office hours: Monday to Friday, 9:00 to 18:00 Pakistan time (PKT, UTC+5).
Behind every project is a company with 1,200+ developers and 85+ management professionals, including group-company employees. Every build follows the same five steps, and the full project starts only after you approve the free pilot.
Before you commit to the full project, we build 2 to 3 of your key modules as working software, free of charge, ready in about 2 days. Your team tests the pilot, and the full build starts only after you approve it.

A fintech software development company builds the software that moves and manages money: payment platforms, lending systems, digital wallets, banking apps and the ledgers behind them. The work goes beyond normal app building because the code handles regulated data, real funds and strict audit requirements. Timeline Digital builds these products end to end with encryption, double-entry ledgers and audit trails designed in from the start.
Fintech software development services cover mapping the money flows and regulated data, threat modelling, the ledger and payment flows, web and mobile apps, payment, KYC and banking integrations, reconciliation and security testing, deployment on AWS or Azure, and SLA support after launch. Timeline Digital delivers them as one project through five steps, starting with a free pilot of 2 to 3 key modules.
Timeline Digital does not publish prices for custom software, because every project is custom. The price is set in three steps: we analyse your requirements, build a free pilot of 2 to 3 key modules, and after you approve the pilot we agree the scope, milestones and commercial terms in writing. Any change request outside the approved scope is reviewed and agreed with you before extra work begins. In fintech the main cost drivers are the number of payment and banking integrations, the ledger and reconciliation rules, the approval controls and the security testing your regulator expects. For market ranges, see the custom software development cost guide.
We design with PCI-aware practices: cards are tokenized through a vetted provider so raw numbers never touch your servers, data is encrypted with AES-256 at rest and TLS in transit, and secrets live in a managed vault. Every balance change and admin action writes to an immutable audit log, and high-value operations need maker-checker approval. We hold no certifications; compliance is confirmed per project.
We build payment platforms and gateways, lending and loan-origination systems, digital wallets, banking dashboards, billing and subscription engines, and reconciliation tools. We also build the parts that decide whether a fintech survives audit: double-entry ledgers, statements, dispute handling and reporting. We scope each build around its money flows and the rules that govern them.
There is no fixed timeframe: the schedule for your fintech platform is set from your requirements in the Plan step. The free pilot of 2 to 3 key modules is ready in about 2 days, and with 1,200+ developers we have the capacity to deliver a focused system in as little as 2 weeks. Money software needs an audit trail and reconciliation testing, and the plan allows for them. The full build starts once you approve the pilot.
If your product touches card data, PCI DSS applies, but the scope depends on how you handle it. Tokenizing cards through a provider such as Stripe or Adyen keeps most cardholder data out of your systems and reduces scope. We design the architecture and document the controls your assessor asks for. Assessment and attestation are yours to obtain; we hold no PCI DSS certification.
Yes. Fintech app development covers iOS and Android apps for wallets, lending, payments and banking, native or cross-platform, on the same secured backend and ledger as the web platform. Mobile adds biometric login, secure token storage on the device, and notifications that never carry sensitive data. See our mobile app development service.
Yes, through vetted providers. We wire identity verification (KYC), sanctions and AML screening, and open-banking data or payment initiation through the providers' APIs, such as Plaid in the US, instead of building regulated checks ourselves. Which providers you can use depends on your licence and market. We are not partners of any of these providers.
Use a white-label or banking-as-a-service platform when a standard product is enough and speed matters most; you accept the provider's rules and fees. Build custom when your product rules, ledger or user experience are the business. Many fintechs do both: they launch on a provider's regulated rails and build their own product and ledger layer on top.
Not published. We have no fintech case study and claim no banking clients or partnerships. We can show our own free installment management software and invoicing app (not regulated fintech), and an anonymized public-sector platform in Qatar with roles, audit logs and approvals. The free pilot lets your team test the core money flow first.
Yes. An NDA can be signed before you share sensitive details such as your product rules, loan models or provider contracts. The source code, designs and documentation transfer to you on full payment; see IP and source code ownership for the terms.
