Leadsie vs AgencyAccess: Which Client Onboarding Tool Wins in 2026?

The 60-Second Verdict

Most comparisons of these two tools are written by one of the two vendors. This one isn't — we make a competing product, and we'll flag our bias now so you can weigh it.

Both tools solve the same core problem. You send one branded link, your client clicks through each platform's official OAuth screens, and ad accounts, pages, and analytics land in your dashboard instead of a two-week email thread. Both store no passwords. Both keep your access intact if you cancel, because permissions live inside Google and Meta, not inside the tool.

Where they differ:

Choose Leadsie if you already use it happily, your CRM is GoHighLevel, or your onboarding volume swings month to month and rollover credits absorb the spikes.

Choose AgencyAccess if you want intake and access in one flow, deep white-label branding, predictable pricing, and time to evaluate — its 30-day trial is twice Leadsie's.

Both are competent. Neither is the only answer. The section after pricing covers what neither vendor volunteers.

Intake Forms: The Biggest Functional Difference

This is the fork in the road.

AgencyAccess builds intake questions into the onboarding flow. While your client is connecting Google Ads, the same flow asks for monthly budget, target cost per lead, and competitor names. The client answers once, in context, and your strategist starts work with everything in hand.

Leadsie collects access only. Intake is a separate tool: Typeform, Google Forms, or your CRM. That means two links, two sessions, and two chances for the client to drop off.

AgencyAccess's own comparison of the two tools makes this its lead differentiator, and it is a real one. The practical question for your agency: how much information do you collect at onboarding? If the answer is "just access," Leadsie's simplicity is a feature. If the answer is "access plus a dozen business details," one flow beats two.

Branding: Logo in a Box vs Full White-Label

Both put your logo on the client-facing flow. The depth differs.

Leadsie covers logo, brand colors, website embedding, and multi-brand management on its Pro plan. That covers most agencies' needs.

AgencyAccess goes further: custom subdomain (clients see your-agency.agencyaccess.co instead of a generic URL) and editable copy — headlines, instructions, and button text in your voice. If your onboarding flow is the first thing a client touches after signing, that control is worth something.

If branding is a checkbox for you, it is not a reason to pick one over the other. If you sell white-label services to other agencies, AgencyAccess's subdomain is the stronger tool.

Integrations: Count the Ones You Use

Leadsie advertises 31+ platforms. AgencyAccess advertises 25+. Vendor counts are self-reported and include edge cases, so treat the numbers as marketing, not spec sheets.

Both cover the core ad stack: Google Ads, GA4, Google Tag Manager, Search Console, Merchant Center, Business Profile, Meta Business Manager, Facebook Pages, Instagram, LinkedIn, TikTok, Pinterest, Snapchat, and Microsoft Ads. Both cover Shopify, HubSpot, Klaviyo, and Mailchimp.

Two checks that matter more than the headline count:

1. List the platforms your agency actually touches. If YouTube Studio or Google Business Profile is in your retainers, verify it on each vendor's integrations page before you commit.
2. Check your edge cases. WordPress and Stripe appear on AgencyAccess's list and not clearly on Leadsie's. If those matter to your onboarding, that settles the question.

Pricing: Credits vs Flat Rate vs Invite Limits

Three models sit in this comparison, and they behave differently as you grow.

Leadsie: credits. Starter $49/mo includes 3 client onboardings. Agency $107/mo includes 10. Pro $299/mo includes 50, plus API access. Overages come in $50 blocks per tier (3/5/10 credits respectively), unused credits roll over for 3 months, and all plans carry a 30-day money-back guarantee. Predictable in steady months, lumpy in launch months: onboard 15 clients in one month on the Starter plan and you will pay $49 plus overage blocks.

AgencyAccess: flat rate with invite caps at the bottom tier. Starter $44/mo ($33/mo billed annually) includes 5 invites. Premium $99/mo ($74 annual) removes the invite cap. Agency $199/mo ($149 annual) adds multi-brand. The 25% annual discount is the largest in this comparison, and there are no overage fees by design.

The third model, for reference: our own plans (Starter $29/mo, Growth $79/mo, Scale $149/mo, with annual discounts) price by client volume per month — 5, 20, and 50 respectively — with no credit math and no invite caps. We include this here because we said we'd flag our bias, not because it decides the comparison.

For volume planning, the honest math: onboarding 8–10 clients a month puts you in Leadsie's Agency plan at $107 or AgencyAccess's Premium at $99 ($74 annual). Onboarding 3 clients a month puts both vendors' entry tiers in play, and the difference is $5 a month plus what each tier limits. One caution: AgencyAccess's own comparison of the two quotes Leadsie's older pricing ($99/$249, $30 overages). Leadsie's live page lists $107/$299 with $50 blocks — vendor comparisons age fast, which is one more reason to verify on the live pricing page before you buy.

Security: The Same Where It Counts

There is no meaningful security difference between these two on the fundamentals:

• Both use each platform's official OAuth flow. Clients never hand over passwords.
• Both store permissions inside Google, Meta, and the other platforms — canceling either tool does not revoke your client access.
• Both are GDPR-compliant and use official APIs.

Questions worth asking both vendors, because neither answers them on a pricing page: where are OAuth tokens stored at rest, do refresh tokens rotate automatically or do clients reconnect manually when access expires, and can you export an audit trail of who granted what, when. Token expiry is the failure mode agencies discover six months in, when a campaign stalls because a token silently lapsed. Ask before you commit, not after.

What Neither Vendor Puts on the Pricing Page

Three operational details that surface after purchase, drawn from what agencies ask us when they are switching:

Automatic token refresh. Platforms expire OAuth tokens on their own schedules. Some tools reconnect them automatically; others require the client to re-authenticate. Automatic refresh is the difference between a dashboard that stays green and a Tuesday scramble.

Audit logging. When a client asks "who still has access to our ad account," the answer should come from a log, not from memory. Check what each tool records about grants, views, and revocations.

API access. If you want onboarding events to flow into your own systems — update the CRM, open a task, notify the account lead — verify whether a public API exists, or whether you are wiring Zapier recipes for everything.

Neither vendor leads with these. Both deserve a demo question.

The Third Option, Stated Honestly

We built AuthHub, so weigh this section accordingly.

AuthHub fits when you want the access-and-intake combination (like AgencyAccess) at a lower entry price ($29/mo), with automatic token refresh, Infisical-backed token storage, audit logs, and API access included. For a three-person agency onboarding a handful of clients a month, it is the cheapest way to get the full feature set.

AuthHub is not the right pick if your CRM is GoHighLevel and you want a native integration — Leadsie has it and we connect through Zapier. It is also not the pick if you are already on either tool and nothing hurts. Switching tools costs a day of setup and re-training; churn that only for a concrete gap.

The full feature-by-feature breakdowns are in our AgencyAccess alternative comparison and our Leadsie alternative comparison, and the three-way table lives in our Leadsie vs AgencyAccess vs AuthHub comparison.

Leadsie vs AgencyAccess: FAQ

Which is cheaper, Leadsie or AgencyAccess? AgencyAccess's Starter is $44/mo ($33 annual) against Leadsie's $49/mo. At the unlimited-invite tier, AgencyAccess Premium is $99/mo ($74 annual) against Leadsie Agency at $107/mo. Leadsie charges $50 overage blocks; AgencyAccess has no overage fees above Starter.

Does either tool store my client's passwords? No. Both use each platform's official OAuth consent flow, and permissions live inside the platforms — so access survives canceling either tool.

Which has more integrations? Leadsie advertises 31+, AgencyAccess 25+. Both cover the standard ad and social stack, so verify your specific platform list rather than choosing on the headline number.

Can I collect intake information and access together? AgencyAccess includes intake questions in the onboarding flow. With Leadsie, intake runs in a separate tool and needs its own link or form.

Which trial is longer? AgencyAccess offers 30 days without a credit card. Leadsie offers 14 days.

Do I keep client access if I cancel? Yes, with both. Permissions are granted inside each platform, so canceling the tool does not revoke what clients granted.

Sources and Verification Notes

Pricing and feature claims were checked against both vendors' live pricing pages in September 2026 (Leadsie: $49/$107/$299 monthly with $50 overage blocks; AgencyAccess: $44/$99/$199 monthly, $33/$74/$149 annual). Platform counts, agency counts, and review ratings are each vendor's self-reported figures and change over time — verify against the live pricing pages before purchase.

On reviews: Leadsie's site advertises 4.9/5 from 55+ verified reviews. G2's public profile for Leadsie currently shows 4.8/5 from 66 reviews. Both are strong; the gap between a vendor's curated number and the open review platform's number is normal and worth knowing. If you want the market's own alternative map, G2's Leadsie alternatives list is the neutral starting point.
