Subscription

Your monthly fee

Covers platform access, team seats, features, and support level. Predictable. Never changes by surprise. Cancel anytime.

Wallet

Prepaid balance in euros

Every completed response and every email sent draws from this balance automatically. Always shown in euros — never converted to credits or points.

Welcome pack

Two gifts. One activation.

When you activate a plan, you receive a one-time welcome pack with two independent components: response credit (in euros) that covers your first responses, and free email sends for your first campaigns. Both are consumed before your wallet is touched.

Response credit

A euro balance that covers completed responses before your wallet is charged. Visible as a separate line in your billing dashboard — you always know how much is left.

Free email sends

A fixed number of outbound survey campaign emails. Consumed before wallet charges apply. Independent from the response credit — each runs to zero separately.

One pack per account, ever. The welcome pack is assigned once at first activation and never renewed or accumulated. If you start on Free (€20 credit) and later upgrade to Pro, you keep the €20 — you don't receive the €40 pack again. To receive the Pro pack, activate Pro directly without going through Free first. The pack never expires by date — it runs out by use only. For scale: the Team credit (€60) covers roughly 1,000 responses on a 10-question survey.
Response pricing

You pay for complexity, not question count.

The per-response cost scales with the longest path a respondent can actually follow through your survey — not the total number of questions defined. A 50-question survey where the longest branching path is 12 questions is priced like a 12-question survey.

The complexity formula

price = base_rate × √(Q_flow / 10)
base_rateyour plan's base price at 10 questions
Q_flowmax questions in any path through the survey (calculated on publish)
10reference length
The square root means short surveys get a much lower rate than long ones, but the curve flattens: going from 50 to 60 questions costs far less extra than going from 5 to 10.

Calculated and shown before you publish. When you go to publish a survey, Dayalogs shows you the max flow length, the per-response price, and an estimate for 100 / 500 / 1,000 responses — so there are no surprises. Partial or abandoned responses cost nothing.

Extra users · Team plan

More seats cost less per seat as you grow.

Extra users on the Team plan are priced with a progressive formula: €15 × n0.80, where n is the number of additional users above the 3 included. The effective cost per user falls smoothly — no tiers, no cliffs. Every user added always increases the total, never suddenly drops it.

Reference prices (Team)

3 users always included in the €100/mo fee. The table shows the extra monthly cost for seats above that.

Extra users (n)Total extra / mo
1 extra (= 4 total)€15.00
3 extra (= 6 total)€36.12
5 extra (= 8 total)€54.36
10 extra (= 13 total)€94.64
17 extra (= 20 total, max)€144.69

How it works

The cost is recalculated each time you add or remove a seat. Adding user n+1 always costs less than adding user n — but always adds to the total.

Mid-month changes are prorated daily: if you add a seat on the 20th, you're charged for the remaining days of the billing cycle only.

Formula
€15 × n0.80
The effective rate per seat falls from €15 at 1 extra to ~€8.50 at 17 extra (the 20-seat cap).

At n=1 the cost is always exactly €15 — the first extra user is never penalised. Adding a user always increases the total; the discount only flattens the curve.
Other wallet costs

One more thing drawn from the wallet.

Besides responses, one other action charges the wallet: survey campaign email sends. AI is never charged — you bring your own.

Campaign email sends

When Dayalogs sends personalised survey links to your audience via email, each send is charged. Bounces within 24h are automatically refunded.

AI usage — bring your own

Dayalogs does not sell AI operations. You connect the AI you already use — Claude, ChatGPT, Cursor, or any MCP-compatible client — and any AI usage is billed by your AI provider, not by Dayalogs.

Wallet

Your balance. Full control.

The wallet is your prepaid euro balance. Top up manually (€10–€500), set automatic recharge rules, configure spending alerts, and cap monthly spend. Everything is visible in real time.

Top up anytime

Add €10–€500 manually from your billing dashboard. Balance never expires. Enterprise can top up via invoice for large amounts.

Auto top-up

Set a threshold (e.g. €20) and a recharge amount (e.g. €100). When balance drops below, your saved card is charged automatically.

Alerts & monthly cap

Email alerts at 50%, 30%, 20%, and €0. Set a hard monthly cap — when reached, surveys pause automatically until you lift it or the month resets.

What happens if your wallet reaches €0

1
Surveys pause gracefully — respondents see a generic "temporarily unavailable" message.
2
48-hour grace period. Add any amount and surveys reactivate immediately.
3
After 48h, surveys stay paused. All data — responses, audiences, settings — is preserved. Nothing is deleted.
4
Reactivation takes under 1 minute once balance is added.

Frequently asked questions

What counts as a "completed response"?
Any response where the respondent reached a final page — a full completion, a demographic screen-out, or a quota-full end. Abandoned or partial responses cost nothing.

Attention check exits — terminal pages triggered by quality-check questions you configure in the survey flow — are not billed. You can still download those responses, but they never count as completions.
How does the complexity pricing work in practice?
When you publish a survey, Dayalogs calculates the longest path any respondent could follow (accounting for branching logic). That number determines the per-response price, which is shown before you confirm the publish. A 40-question survey where the longest branch is 8 questions costs like an 8-question survey.
Can I see my exact wallet spend in real time?
Yes. Every wallet deduction is logged with timestamp, survey name, and operation type (response / email send). Your billing dashboard shows a filterable transaction history and a projection of how many days your current balance will last at your recent spend rate.
What if I start on Free and want the Pro welcome pack?
The welcome pack is assigned once per account at first activation. If you activate Free first, you receive the Free pack (€20 credit, 0 email sends). Upgrading to Pro later does not add the Pro pack. If you want the Pro pack (€40 credit + 200 email sends), activate Pro directly without going through Free first.
Do I pay for AI usage?
Not to Dayalogs. You connect the AI you already use — Claude, ChatGPT, Cursor, or any MCP-compatible client — and any AI usage is billed by your AI provider. Dayalogs never charges your wallet for AI.
Can I pause a specific survey to control costs?
Yes. From the billing dashboard you can pause any individual survey independently, without affecting others. You can also set a hard monthly cap: when reached, all surveys pause automatically until you lift the cap or the month resets.
Do you offer invoicing for Enterprise?
Yes. Large wallet top-ups for Enterprise can be handled by bank transfer and invoice. Contact your account manager. Monthly subscription invoices are generated automatically by Stripe on each renewal date.
