+ Resyrv vs spreadsheets

Your spreadsheet worked. Until it didn't.

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

Where the spreadsheet runs out of room.

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

The hidden bill.

The spreadsheet owner quits (or retires)

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.

Math errors nobody catches

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 "who's flying Saturday?" texts never end

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.

Compliance gaps become legal exposure

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.

Selling a share becomes painful

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

You already have the data.

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

Frequently asked.

Is a spreadsheet enough to manage a shared aircraft?

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.

Can I import my spreadsheet data into Resyrv?

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.

How long does migration from a spreadsheet take?

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.

Will my partners trust Resyrv more than the spreadsheet?

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.

What if my partnership is happy with the spreadsheet?

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.
