Platform
Everything a process needs, already connected
Most organisations juggle a form tool, an approval tool, shared drives and spreadsheets. FlexApp puts them in one place, so work moves from request to decision to report without anyone retyping it.
Workflow
Approvals that move on their own — designed by your business teams, with a full record of every decision.
Learn moreForms
Replace paper and spreadsheet forms with online forms your own team builds and changes.
Learn moreDrive
Every company document in one secure place — easy to find, approve, sign and ask questions of.
Learn moreDashboards & Reports
Up-to-date dashboards and reports your managers build themselves — or simply ask for in plain language.
Learn moreAI Assistant
Ask in plain language and get work done — an AI assistant on every screen, using the AI model your organisation chooses.
Learn moreIntegration
Connect FlexApp to your ERP, accounting and other business systems — so nobody re-types the same information twice.
Learn moreMobile & Chat
Approve, chat and share files from anywhere — on the phone app, WeChat or a browser.
Learn moreSecurity & Admin
One sign-in, the right access for each person, and every subsidiary's data kept apart.
Learn moreAI built in
AI that works inside your everyday processes
AI in FlexApp is not a separate chat window. It is part of how requests are prepared, documents are found, receipts are checked and reports are produced, and it always works on your own information.
Describe a process, get a working draft
Tell FlexApp how an approval should run, in your own words. AI drafts the workflow for your team to review and adjust before it goes live.
Ask your documents
Staff ask questions in plain language, such as a policy, a contract term or a procedure, and get answers drawn from your own files, with the source shown.
Reports on request
Managers ask a business question and get a table and a suggested chart, instead of waiting days for someone to build a report.
Receipts and invoices read for you
Expense receipts and supplier invoices are read automatically, details are filled in, and duplicates are flagged before anyone pays twice.
Faster customer service
In the help desk, AI sorts incoming requests, suggests replies to agents and helps customers find answers before they raise a ticket.
Your data, your AI model
Choose the AI provider you trust, including a model that runs on your own servers. The assistant asks before changing anything and respects who can see what.
How a request flows through FlexApp
A staff member fills in a form. It goes to the right approvers automatically, the documents are filed, the accounts are updated and management sees the result on a live dashboard.
Solutions
What organisations use FlexApp for
A few everyday situations FlexApp is built for. Most customers start with one and add more.
Approve requests from anywhere
Purchase requests, leave and payments arrive on the phone or in WeChat with the details and attachments. One tap approves, and the requester sees the decision straight away.
Learn moreExpense claims without paper
Staff photograph receipts, the claim fills itself in and company policy is checked automatically. Finance reviews exceptions instead of every slip of paper.
Learn moreSpending under control
Every purchase is checked against budget and approval limits before it is committed, and invoices are matched to what was ordered and received before payment.
Learn moreHiring, reviews and training in one place
Candidates move through a clear hiring pipeline, appraisals run on schedule and mandatory training is tracked, so HR spends less time chasing people.
Learn moreContracts that never slip
Contracts are drafted from approved wording, signed online and stored in one searchable place, with reminders before renewals and obligations fall due.
Learn moreOne view of the business
Live dashboards show approvals, spending, service levels and project status across departments and companies, without waiting for month-end spreadsheets.

What is FlexApp used for?
Organisations use FlexApp to take everyday processes off paper, email and spreadsheets: approvals, requests, document filing and signing, and management reporting. They add ready-made apps for expense claims, purchasing, budgeting, hiring, customer relationships, contracts, safety, ESG reporting and more.

Can FlexApp run on our own servers?
Yes. FlexApp can run in your own data centre or in a private cloud, so your information stays under your control. Contact us about hosted options.
