How It Works

From your call data to a finished schedule
in three steps

No workforce management training needed. You bring the numbers; the tool does the math.

📞
Step 01

Tell us about your calls

Upload a report from your phone system and we'll work out when your customers call, how long calls take, and how many calls to expect next week. No report? Pick the pattern closest to your day and type in your call volume.

🎯
Step 02

See how many people you need

Click Calculate. You get the number of people needed in each half hour to hit your answer-speed goal, with a heat map that shows your busiest times at a glance. Add your hourly pay to see the weekly cost and the cost per call.

Headcount by half hour, total staff needed, and what it costs
📅
Step 03

Build shifts and share them

The Schedule Builder turns headcount into shifts with lunches and breaks placed around your busy periods. The Roster Optimizer assigns those shifts to your people within your hours and rest rules. Then send your team one link to see their week.

Everything from the first forecast to the posted schedule

Each part works on its own, and each one feeds the next.

Staffing Calculator

Know how many people you need, half hour by half hour

The calculator uses Erlang C, the standard formula for call center staffing, with your call duration, answer-speed goal and time lost to breaks, training and absences. A color-coded heat map shows where your week is busiest, so you can see the crunch times without reading a spreadsheet.

Schedule Builder

Shifts that follow your call volume

Set your shift length, opening hours and break rules, and the builder creates start times that put more people on when calls peak. Lunches and breaks are staggered so they don't all land in your busiest half hour. Drag any break on the timeline to adjust it.

Coverage Check

See the gaps before your customers do

A chart compares the people you need with the people actually on the phones in every half hour. Red marks the times you're short, green the times you have extra. With your hourly pay entered, you also see what the extra coverage costs and what it would cost to fill the gaps.

Roster Optimizer

Put real people on those shifts

Tell it how many employees you have and your rules: maximum hours and days per week, minimum rest between shifts, weekend limits. It assigns everyone a consistent weekly line and shows total hours, payroll and overtime. Check the result against your local labor rules before you post it.

Built by a WFM analyst

The tool I wished existed when I ran a 200-seat contact center

“

After 7+ years managing workforce planning for a 24/7 healthcare contact center, I built the tool I wished existed. Paste your call data, set your targets, and get a mathematically precise staffing plan — headcount, shifts, breaks, and a full employee roster — in minutes.

Dimitry Glater
Workforce Management Analyst & Founder, BuildMyShift
★★★★★

"I used to spend half a day every Sunday building next week's schedule in Excel. Now I paste our ACD data, hit Calculate, build schedules, and the entire roster is done in 10 minutes. The break optimization alone saved us from SLA misses."

Sarah K. Contact Center Manager, Insurance
★★★★★

"The heat map was a revelation. We immediately saw we were under-staffed from 8:30-10:00 every day — something we'd been guessing about for months. The Erlang C math just makes it obvious."

Marcus T. Operations Manager, E-commerce
★★★★★

"We use it to sanity-check our WFM vendor's staffing numbers every week. Same Erlang C math, same answer — and I can prototype new schedule scenarios in minutes instead of waiting for our analyst to run them."

Priya N. Workforce Planning Lead, Fintech
