"Our spreadsheet isn't enough anymore." That's the tenth sentence clients bring to Biber Dijital. Tens of thousands of rows, colour coding, tangled macros, draft versions flying through email… at some point, the spreadsheet stops being the solution and becomes the problem. That's where we come in: we build custom software for you. Here's the recipe.

From spreadsheet chaos to a panel — same data, but now it tells a story.

We ask first, write code later

Custom software isn't "the off-the-shelf thing, but slightly different". A real software project starts by understanding how your company actually operates. In week one we show up with questions: "How does a sale flow?", "What data travels where?", "Who does this, how often?", "When does it break?"

We call this stage process mapping. The output is a flow diagram that surfaces bottlenecks, redundant steps and hidden copy-paste work — things even you don't notice from inside the company. Then we overlay "software can handle this" notes.

Biber note: The biggest custom-software mistake: encoding the broken process as-is. Before we code the process, we improve the process. Digitising a broken workflow just gives you a faster broken workflow.

MVP: ship small, grow later

Every custom software project starts as an MVP (Minimum Viable Product) — the leanest version of the system, must-have features only, everything else parked. That achieves three things at once:

  • Fast feedback — a real product in users' hands in 2–3 months
  • Budget flexibility — critical first, rest spread over months
  • Early learning — first use reveals real needs

After that, we move in two-week iterations (sprints). Each sprint ends with a usable new feature, we test it together and re-prioritise. At every sprint planning the client re-asks, "what would unblock us most?"

Tech selection: the right tool for the job

There's no single correct stack for custom software. We pick per project:

  • Backend: Node.js (NestJS), Python (FastAPI, Django), or Go when workload is heavy
  • Database: PostgreSQL as primary; Redis, MongoDB, ClickHouse as needed
  • Admin panel: React, Next.js or Astro (usually Next.js for admin)
  • Queues and schedulers: BullMQ, Celery or Cloudflare Queues
  • Hosting: AWS, Google Cloud, Cloudflare Workers — depending on load

Is this a cloud-first workload, a local tool, a panel that mobile also hits? These questions drive the stack. The "let's use whatever's trending" approach becomes a maintenance nightmare two years later.

Five systems rotating around one API — when they talk to each other, everything clicks.

Integrations: software that can't connect is deadweight

Custom software earns most of its value from speaking with the tools you already use. Your accounting software, your e-commerce platform, your carrier, WhatsApp Business API, bank POS systems. At project start we list every integration point, and document for each which API we'll call and what data format we'll exchange.

Common integrations we see: Stripe / Adyen for payments, Shopify / WooCommerce for storefront, Amazon / eBay / Etsy for marketplaces, FedEx / UPS / DHL for shipping, WhatsApp Business API for conversations. Each has its quirks; we open the hood and arrange the wiring.

Security and GDPR: clean kitchen, clean records

Custom software usually means sensitive data. Customer info, financial data, identity documents. From day one, we apply these rules:

  • Passwords hashed with bcrypt/argon2, never stored as plaintext
  • JWT / OAuth for API access, rate limiting enforced
  • All traffic HTTPS, database over TLS
  • Column-level encryption for sensitive fields
  • GDPR readiness: data-processing inventory, retention periods, a UI for erasure requests
  • Audit log — who did what, when — all recorded

Delivery and ownership: the code is yours

When we deliver custom software, the code is yours. GitHub / GitLab repos are transferred to your account, server access handed over, documentation (API, deployment, operations) prepared. Even in a break-up scenario, nobody's taking your business hostage.

From there, clients who want to continue with us do — maintenance, new features, performance work. Those who don't move on with their own team. Either way, the code is readable, tested and standards-compliant; handoff is smooth.

Biber note: Sharing the code with you isn't the same as "you're on your own now". 6 months of free maintenance are included; after that, monthly care plans. Custom software isn't a one-off — it's a living system.

The payoff: infrastructure that accelerates you

Well-built custom software fades into the background so quietly you forget it's there. Workflows run themselves, reports emerge automatically, errors drop, the team moves on to different work. Every custom-software project we ship saves an average of 10–14 hours per week of manual labour.

If you've got a tangled process, a spreadsheet that outgrew itself, or a SaaS idea from scratch — a coffee-length conversation will map the landscape. Or check the packages; software pricing is laid out transparently.
