From the work order to the paperwork

Capture it. Connect it. Keep it.

Give each job a useful record, prepare the customer paperwork, and keep a portable copy of your collection.

01 · CAPTURE

Tie every detail to the job

Link work notes, labor time, outcomes and references to an aircraft and work order. Add original photos and supporting files to the relevant record.

02 · INVOICE

Turn work into clear invoices

Build quotes and invoices from your work, generate a PDF on the device, and share it through your chosen app. Record payments and preserve issued-document history.

03 · BACK UP

Protect records and originals

Create a password-encrypted backup of saved records and original attachments. Choose where to save it and restore it when you need to move or recover your collection.

04 / ASSETS

Track tools and parts together

Organize parts, quantities, suppliers, costs and installation or removal notes. Keep tool serial numbers, locations and user-entered calibration dates close at hand.

05 / EVIDENCE

Keep experience evidence organized

Keep certificate copies, training, recent-experience periods and Inspection Authorization activity evidence. The app records your information; it does not determine legal qualification.

06 / EXPORT

Export the records you need

Create local PDF and CSV exports and share original files when you choose. Normal recordkeeping works offline, with light and dark appearance options.

Inside A&P Ledger

Keep the whole workday in view.

Move from today’s work to customer paperwork and the records behind it. Example records shown.

Quick start

Your first few minutes.

  1. Organize the job

    Add the relevant customer and aircraft details, then link a work order and work records. Record your notes, labor time, outcomes and references.

  2. Keep evidence with the work

    Attach the original photos and supporting files you need. Keep parts, tools and qualification evidence in their relevant records.

  3. Prepare customer paperwork

    Build a quote or invoice, review its details, generate a PDF on the device and choose a sharing destination. Record payments and retain issued-document history.

  4. Make a protected backup

    Resolve pending photo-recovery items or share their originals separately. Export a password-encrypted backup and keep its password safe; there is no password-recovery service.

More than a job list

Keep the context with the record.

  • Aircraft and customer details, linked work orders and record history.
  • Parts, quantities, suppliers, costs and installation or removal notes.
  • Tools, serial numbers, locations and user-entered calibration dates.
  • Certificate copies, training, recent-experience periods and Inspection Authorization activity evidence.
  • Local PDF and CSV exports, original-file sharing, and light or dark appearance.

Your records stay on your device

No Sunimod account or record server is required. Normal recordkeeping works offline. Optional store billing, external links and the destinations you choose for sharing can use online services.


Backups are manual and password-encrypted. There is no automatic multi-device sync or password-recovery service. Resolve pending photo-recovery items before backing up or share their originals separately.

Free capacity · Optional monthly Pro

Start with the essentials.

Free

  • 3 clients and 2 aircraft.
  • 3 active work orders, 10 tools and 25 attached files.
  • 3 issued quotes or invoices combined per calendar month.
  • No entry-count limit for work records, parts, qualification or experience evidence.

Pro

The optional monthly subscription removes those app count limits. Device capacity and supported file-size limits still apply. See Availability for access and pricing information.


Reading and editing existing records, exports, recording payments and encrypted backups remain available when Pro ends.

When offered, Pro renews automatically unless canceled through the store used for purchase. Apple and Google purchases are separate. Restore purchases uses the same platform account; a backup transfers records, not a subscription. Manage cancellation and refunds through the relevant store.

A recordkeeping tool for mechanics. A&P Ledger does not determine legal qualification, approve airworthiness or authorize return to service. Worksheets, portfolio exports and invoices do not replace required maintenance entries or signatures. Review the applicable current rules and your actual privileges.
