Requests and approvals app

Concept for a 300-person company · HR, operations and finance teams

A 300-person company handles around 150 requests a month: laptops for new hires, leave, purchases, travel, building access. Each one starts as an email, gets copied into a shared spreadsheet and then waits in a manager's inbox.

  • One form per request type. Each type asks only for what it needs, with amounts, dates and attachments checked before it can be sent.
  • Routing rules. Requests go to the right manager by team and amount, and escalate automatically if they sit for more than two days.
  • One-click decisions. Managers approve or reject from email or their phone, with an optional comment.
  • Asset handover and return. Equipment is signed out and signed back in, so every item has an owner.

01 · The problem

What usually goes wrong.

Internal work usually grows around spreadsheets, shared inboxes and group chats because they are quick to start. Later the problems show up: records are duplicated, nobody knows who can change what, approvals get lost in messages and reports take hours to build. The business grows, but daily work gets harder to trust.

02 · The fix

What we build.

We map how the work really happens: who does what, which decisions are made and where things go wrong. Then we build one simple app with records, search, approvals, owners for each task, a history of changes and reports. It uses the words your team already uses, and it stops incomplete or wrong entries from slipping through.

  • Map of who does what
  • Dashboards and reports
  • Records you can search and filter
  • Approvals, permissions and change history
  • Data import and connections to your tools
  • Training for your team
03 · Launch

How we switch it on safely.

The first version replaces one complete process, not the whole company. We clean and import your existing data and test it with real users, including the awkward cases, before everyone switches over. After launch we look at time saved and errors to decide what to improve next.

Is this for you?

A good fit if:

  • Important work runs through spreadsheets and email
  • Your current software almost fits but needs constant workarounds
  • You need logins, approvals, history or proper reports

Works with: CRM, accounting, inventory, calendars, file storage, email, Microsoft 365, Google Workspace and custom APIs.

When not to hire us

  • If an off the shelf tool already does the job without workarounds, buy that instead.
  • The first version should fix one process, not the whole company.
  • Messy old data may need cleaning before it can be moved.
