THE OLD WAY

DTS voucher prep is brutal.

Hours lost

Tracking down crumpled receipts. Calculating hotel folio taxes, foreign currency conversion, IDL crossings.

Forgetting to claim reimbursable expenses

Airport POV mileage, parking, self procured airfare.

No alert when certain expenses are missing

Leaving money you're owed on the table and not knowing about it.

HOW IT WORKS

SNAP, TAP, GET YOUR MONEY BACK.

Simply upload your receipts. The app builds your complete DTS voucher automatically.

SNAP
Add your receipts

Camera, Photos, share from Mail and Files. Just get them into the app as you travel and watch your voucher take shape.

TAP
Review what it built

Once your travel is marked complete, the app will automatically alert you of possible missing expenses allowing you to add them quickly or dismiss with a tap.

GET YOUR MONEY BACK
Export and Submit

After review, the app exports a single, easy to read pdf that contains each individual expense line and every receipt for upload into DTS. Use the in app checklist to mark off expenses as you enter them.

ALREADY FILED?

We can still find money you left behind.

Upload old DTS vouchers or trip records. We’ll review what you claimed and surface likely missed expenses — airport mileage, parking that should have been terminal, per-diem adjustments, Non-A situations, and more. A lot of people recover real money from trips they already thought were done.
BUILT FOR REAL TDY LIFE

Everything you actually need.

Handles stacks of photos

Shoot a whole packet of receipts. The app figures out which pages go together so you don’t have to sort them by hand.

Gets your per-diem right

Knows on-base vs off-base, travel days, and when you need a Non-A. Uses the real rates so you don’t have to look everything up.

POV mileage that just works

Set your home address once. Capture an airfare. The app suggests from home → airport or lodging, calculates real driving distance, and applies the current GSA rate.

Smart advisories, not nagging

“Missing airport mileage”, “Non-A status needed”, “Date conflict”, “Possible dual lodging”. One tap to resolve or acknowledge. Yellow/red borders show status at a glance.

Export packet that finance loves

One PDF with every receipt image in order + a clean DTS-style line-item checklist. Exactly what you need to copy into the official system.

Keeps working when you’re offline

Close the app or lose signal. When you’re back online the receipts are ready. No need to babysit it.

Audit past trips

Upload old DTS vouchers. We’ll flag expenses you probably should have claimed — airport mileage, parking, per-diem adjustments, and more.

POV mileage that calculates itself.

Frequently asked questions

Is this an official DoD or DTS app?

No. TDY Slayer is built by Southwind Digital LLC, a small commercial company. It is a private tool designed to make the official DTS process faster and more accurate. You still file in the real DTS system.

How well does it actually read receipts?

Good on normal receipts and strong on the messy multi-page folios that usually cause problems. You can edit anything, and we’ve tested it on real packets from a lot of different bases.

Does it handle foreign currency and OCONUS trips?

Yes. It converts foreign receipts to USD using the official rates for that date, and it handles per-diem for overseas and remote locations too.

What about Non-A letters and on-base vs off-base?

It spots when you’re on base or need a Non-A letter and asks the right questions. Once you confirm, it uses the correct rate for those nights.

Is my data private?

Receipts stay on your phone. They’re only sent out when the app needs to read them, and we don’t keep or train on your information.
