Staffing Agency Client Portal: Shifts, Timesheets and Workers in One Login

A staffing agency client portal lets the businesses you supply request shifts, see who is coming and approve timesheets, while workers accept shifts and keep their certificates current. Describe your agency to Mythex and it builds both sides on one real database, with logins and roles, in a live preview you change by chatting.

Who it's for

Temp and contract agencies whose client requests arrive by phone and email, whose timesheets are paper or photos, and whose biggest weekly argument is over hours nobody approved.

What you can build

Clients request shifts by site, role, date and headcount
Clients see who is booked with their certificates
Supervisors approve timesheets before payroll
Workers accept or decline offered shifts
Workers upload renewed certificates
Site profiles with where to report and PPE

What the client side must show

A client supervisor wants to know, for tomorrow's shift, exactly who is coming, what time and whether they hold the forklift or food hygiene certificate the site requires. Show each booked shift with worker name, role, start time and relevant certificates. Let the client raise a new request with site, role, date, start and end time and number of workers, and see its status move from open to filled.

Timesheet approval is where the portal pays for itself

Disputed hours are the main source of friction in temp work. Each week the supervisor sees the hours each worker submitted, adjusts or approves, and the approval is stamped with name and time. Only approved hours flow into invoices and pay, so the invoice that arrives matches what the client already agreed, and payment comes faster.

The worker side

Workers see shifts offered to them, accept or decline with one tap, check confirmed shifts with the site address and instructions, submit hours, set availability and upload new certificates when they renew. Keep reliability notes and client feedback internal; workers should see only what they need for their shifts.

Mistakes to avoid

Do not give clients access to other clients' data or to worker pay rates; separate charge rates and pay rates by role. Do not make worker sign-up demand every document upfront, since applicants on phones give up. And do not launch to every client at once; start with one site and its supervisor and iron out the timesheet flow.

A prompt to start from

Build a client and worker portal for my staffing agency. Client supervisors log in to request shifts by site, role, date and headcount, see booked workers with their certificates, and approve weekly timesheets. Workers log in to accept offered shifts, see confirmed shifts with site instructions, submit hours, set availability and upload certificates. Only approved hours count toward invoices.

Questions

Can each client see only their own sites?

Yes. Ask for client accounts tied to their sites, and supervisors only see shifts, workers and timesheets for those sites.

Can workers use it on their phones?

Yes. It works in a phone browser, and on Pro Mythex can also turn it into Android and iPhone apps that open your published app.

Can approved timesheets become invoices automatically?

Yes. Ask for invoices built from approved hours at each client's charge rates, including overtime and night rates.

Is it free to build?

You can build and publish on the Free plan, no card required. Pro at $25 a month adds a custom domain, code editing, export and more credits.

Do I need to know how to code?

No. You describe what clients and workers should see, and change it by chatting.
