+Resyrv vs spreadsheets
Every shared-aircraft group starts with a spreadsheet. A tab for bookings. A tab for hours. A tab for reserves that nobody quite trusts. Resyrv is what you reach for when the spreadsheet has quietly become the thing you argue about.
+Side by side
| Dimension | Spreadsheet | Resyrv |
|---|---|---|
| Conflict-free reservations | Manual: two people can book the same slot before anyone notices | Server validates every reservation against existing bookings; conflicts are rejected |
| Per-member booking rules | Enforced by honor system; bad actors figured out years ago | Lead time, duration, and concurrent-booking limits enforced at reservation time |
| Cost calculation per flight | Someone hand-enters hobbs/tach and multiplies; math errors compound over months | Hobbs/tach logged at flight close; cost rules applied automatically; ledger updates instantly |
| Fuel price handling | Fixed in a cell somewhere; updated when someone remembers | Wet or dry fuel billing per aircraft; fuel purchases logged at flight close post as reimbursements or charges automatically |
| Reserve accruals (engine / prop / avionics) | A tab with accrual logic nobody fully understands anymore | Per-hour or per-month reserves tracked per aircraft; balances visible on every report |
| Squawk tracking | Yellow notepad in the organization, group text, or a separate Doc | Logged from phone; routed to maintenance; resolved with audit trail on the aircraft record |
| Inspection + AD reminders | Calendar reminders someone set up in 2019 on their personal iCal | Hobbs and calendar-based reminders per aircraft; grounding flags block scheduling if overdue |
| Member currency + medical tracking | Usually not tracked; found out at the worst possible moment | Medical, BFR, 90-day, IPC tracked per pilot; bookings block when expired |
| Billing + payments | Venmo, checks, "I'll get you next time" | Stripe card + ACH; every charge itemized on the member ledger; recurring dues; monthly statements; QuickBooks Online and Xero sync |
| Audit trail | Whatever the revision history shows (if it shows anything) | Every change logged with user, timestamp, and before/after value |
| Mobile access | Technically yes; practically miserable | Native iOS app plus mobile web; log flights, squawks, and bookings from the ramp |
| Cost to start | Free | Free trial; paid plans scale with group size (see pricing) |
| Cost at 12 months | Hidden: someone's unpaid weekend time, plus the occasional expensive error | Predictable monthly or annual subscription |
+What your spreadsheet actually costs
Every shared-aircraft spreadsheet has one person who maintains it. When they leave, the group loses their institutional knowledge, the formula logic, and the will to keep up the system. Within six months, entries are sparse.
An accidental hobbs-typo of 12.3 instead of 1.23 posts the wrong charge. It's quietly wrong for months. Reconciling takes hours and damages trust.
The spreadsheet calendar is read-mostly. Nobody trusts it as the source of truth, so the group text becomes the de-facto schedule. You end up with two conflicting records.
An expired insurance endorsement, a missing AD compliance record, an overdue annual: any of these on a spreadsheet is a paperwork failure waiting to become a real one.
A new partner wants to see the aircraft's history, the partnership's financials, and the maintenance record. "It's all in the spreadsheet" translates to "there is no clean record to hand you."
+Migration
Aircraft records, member lists, cost rules, flight history: whatever you have in the spreadsheet can move. Most partnerships start with aircraft and members; flights and financial history are optional depending on whether you want a clean break or a continuous ledger.
+Questions
A spreadsheet works until it doesn't. Most shared-aircraft groups outgrow their spreadsheet when a second aircraft joins, when the group grows past four or five pilots, or when a partner turns over. At that point, the spreadsheet becomes a liability: partial records, argued numbers, and no audit trail.
Yes. Aircraft records, member lists, flight history, and financial transactions can be imported from spreadsheet exports during setup. We also help set up your cost rules so the migrated numbers continue to reconcile cleanly.
Most groups are fully set up within 20 minutes to a day, depending on fleet size and how much historical data you want to carry over. The most common approach is to import aircraft and member records, then let new flights and transactions flow in going forward, reserving historical data in the original spreadsheet for reference.
Usually yes, because every entry has a user, a timestamp, and an audit trail. Partners can see exactly how their balance was calculated, who logged the flight, and when. It removes the "I don't understand this number" friction that spreadsheets create.
Then you don't need Resyrv yet. We'd rather have a partnership using a spreadsheet well than using Resyrv poorly. The groups that benefit most are the ones where the spreadsheet is already cracking: arguments, missed reminders, confused reconciliation, or a scheduler burned out on being the central node.
